I'm losing recordings.
Pixel 1 device
I record and try to rename the file;
I then get told by the app that the file cannot be found.
When I look in the file manager, I see neither the original filename not the filename I tried to rename it to.
I really like this app, but I can't use it if it losses my recordings.
Hey, I am facing some initial delay issues with MediaRecorder class in my app. However, there is no delay with the AudioRecord class. But I need to save file .m4a format.
So the question is how to use the WavRecorder class to save the recording as .m4a file.
Any help would be highly appreciated, thanks in advance.
It would be nice to have possibility to use button to start recording, recording as long as button is hold, and stop recording, when button is released. Ideally, it should work even on locked phone
It would be very useful to record audio as soon as the app opens.
please add support flac, vorbis (ogg) audio codec it would be great

The components (Features) I want to suggest is
This feature must be in this application and This feature will increase the utility of application.
1- Crop
2- Move File
3- Open With
4- Set as
according to my information, this very simple and useful application and all the features are really amazing but I want the suggestion to add some features in the application.
with the help of this feature, the user can edit and crop their voice recording. and users also able to crop or cut clip Which he does not like.
according to my knowledge when I recorded the voice clip save in phone memory and some users have not extra space in phone storage so these features are very useful for that user. The user can able to transfer recording phone storage to memory card storage.
The application original audio player is not bad but sometimes users want to like hear the audio recording clip on their own phone player the help of this feature users can be able to hear the recording on their own phone player. Just simply click on the Open With option and choose your favorite player.

I searched a lot and find that best orm choice for android that supported and recommended by Google is Room.
Here I a put the link for you: Room Persistence Library.
Let me know If you want any help for migration.
I have a large file that was not closed and is now corrupted. Is it possible to periodically save the file while it is recording in order to avoid losing large recordings entirely if the closed properly?
Also, I am looking for information how to recover the file. In particular, I am looking for information about how what encoding the audio is.
One of my apps require record function (NOT its main function), and I found your project is easy to use and highly customize. May I use it for my app?
Please add support for record from Bluetooth devices.
Request: Please provide a file naming convention with an unambiguous date and time representation, where values are ordered from the largest to smallest unit of time.
Reason 1: Current convention does not allow files to be naturally sorted by name.
Reason 2: Current convention is ambiguous for the international users since date and time representation vary by country.
A minimal solution would be to modify the current convention by swapping the day and the year:
2020.05.19 17.31.00
An orthodox solution would be to adhere to an ISO 8601 standard, for example:
20200519173100+0300
Personally, I would prefer something which resembles the default android camera app naming convention, by replacing IMG
/ VID
prefix with REC
or AUD
:
REC_20200519_173100
AUD_20200519_173100
Add high quality bitrates and more formats for recording like MP3 etc.
Audio recorder records sound/voices and also import some files. I've used it well, and I'm still enjoying it. My proposals will be based on voice/sound recording.
It is optimized for a fast start which helps user not to miss important voice recording. Rec has two basic recording format which is Advance audio coding (AAC) and Waveform file format.
Pause and skip silence: During recording, there can be a different level of quiet time when there will be no sound or different level of sound. Within this period, the recorder will automatically filter the surrounding sound level and control recording till the desired sound returns. At first, I thought it might be difficult to come up with this idea, but I think it's possible.
There is what we call ATH (Absolute threshold of hearing). We as humans all possess this which is recorded at 0 decibel SPL and also varies with different people. It is the minimum sound level of tone that an average Human ear with normal hearing ability can hear without any distortion. This concept can be used to achieve the purpose. Whenever there's silence while recording, the app will filter the surrounding sound and react on it accordingly. For example, the app can be set to pause recording if the level of surrounding sound is below the silence barrier, hearing threshold or conversations. This can be detected at different frequencies. E.g.,
1. Silent barrier set as -1db spl
2. The hearing threshold set as 0db spl
3. The conversation set as 1db spl
The units for each silence level will be set in the back end. It will not be adjustable by users.
db spl is the unit to denote the measurement of a sound. It is referred to as decibel of sound pressure level. Since the loudness of a sound varies for different frequencies and not required with its sound pressure level, the pause and skip silence level is possible to implement.
The first image shows how the app looks before the design
The below images shows the settings of the silence features. Only one can be turn on at a time. The skip silence button will activate others when switched on.
The pause and skip silence can be used to achieve a clear recording. It will make users recording concise and accurate. This feature can be used to achieve the desired result in terms of recording. For instance, if I plant my device in a hidden place to record some malicious conversation, only the important voice sound will be captured. Also, the noisy part of a conversation or a sound recording will be filtered out. Only the clear part will be captured. Quiet times will also be filtered out, and space(either internal or external storage) will be used up wisely.
Thanks.
Hi,
I found this copy of your app on Google Play below, just to let you know.
https://play.google.com/store/apps/details?id=com.sain.recorder from this developer
Maybe you could send a DMCA request to Google if you want it ;)
Would be nice if the app could record to FLAC, since it's simply better than WAV in that it's still loseless, but compressed and an open format.
hello
thanks for sharing source code :)
I have question, can we have colorful waveform by this custom view?
RandomAccessFile write will overwrite the original content,so wav file loss 44 bytes data;
I suggest writing 44 bytes of blank data before recording.
and totalAudioLen ,totalDataLen is wrong.(8 bytes smaller)
Thank you
I've been losing recordings lately, at least during the summer of 2020. My current guess it has to do with the timing of renaming the file. I record something, rename it, then get a file could not be found message.
These days I wait until the calculating a waveforms is finished and that avoids the file from getting lost; but, I'd like to rename a file with confidence.
This feature cannot be turned on on Current Version 0.9.7
It's really nice and you added all feature. If you add trimmer functionality like https://online-voice-recorder.com/
it would be more helpful
It will be great if app allows me to organize recordings in some categories or directories. Marking as favourite is not enough.
Thank you for your hard work with this great app! I'm not sure what "save to public dir" means in the settings, but I think adding an option to set the location where recordings are saved would be valuable in this app. A button that opens up the file browser, where the user selects a folder to save the recordings to, would be very helpful for my use case.
Thanks again!
possible bug
Rec audio recorder is an open source audio recorder app that makes audio recording experience enjoyable. It is optimized for a fast start which helps user not to miss important voice recording. Rec has two basic recording format which is Advance audio coding (AAC) and Waveform file format. (WAVE). This app has many essential features that makes it unique. Part of the features are
Audio recording
Playback in background
Playback record
Share record
Record list
Display record waveform
Coloured theme. E.T.C
All these features are fantastic, but I would love to spice it up with some features I believe would add more life to it.
The features I will be proposing are
Record at will: This is a way of recording at the desired period without compulsorily operating your device at the set time. The feature will make it easy to record voices without being noticed. If you want to start recording your conversation with someone in the next 5 minutes, for instance, you don't need to make your action open; else you might get caught. You can easily set the time in advance, and it will start recording when the time is right. This feature can be incorporated in the app settings below the "Record in stereo" feature. A click on it will pop up a page where the recording time can be set.
recording duration: The app currently record to eternity as long as there is enough storage space. It's okay, but incorporating a minimum recording duration will allow users to set the period they want. For instance, if I want to make a 2 minutes voice recording, I can set the duration to 2 minutes and channel my speech to fit the time. This feature can also be in the settings. Clicking on it will enable you to set the minimum duration for recording.
Mock ups/ Examples
The original look of the app
Below are the images for record at will
Setting a minimum recording duration
The automatic recording will make the app more unique by allowing users to record voices automatically. Users can easily set when they want the recording to start. The minimum recording duration is also another feature that will add more value to the app. I will say it's a compliment for the automatic recording feature. Why? Because if the app is set to auto-record, the minimum recording duration can also be set for the recording to stop when the time is right. So they can be said to be an auto start and stop.
Thanks.
I use Android 6.0 (iLA S1, 1920x1080) which has on-screen system buttons, and apparently the application cannot handle such layout properly since it shows its main window under the on-screen buttons, which block access to app UI elements.
Consider the screenshot below:
I was unable to touch Reset or Apply buttons, because they went under the on-screen system buttons.
Please add support for recording audio from an external audio device.
Make it possible to set a custom location to save the recordings.
is it possible for you to add a better compression so that recording takes less of space on the device? currently it is good for m4a format but certainly not enough
Hi! Love your AudioRecorder app.
I'm trying to add it to my workflow but I'm stumped with one issue and I don't know if I need help or if I'm requesting for a new feature/enhancement...
I regularly record/stream with two microphones connected to a Behringer UMC202HD Sound Interface. The resulting stereo track holds two clearly distinct mono inputs that I can separate in my Win 10 DAW (Audacity or OBS).
I connected the AudioRecorder app in my Samsung S7 (Android - USB Audio Input) to a powered USB HUB with the Behringer and 2 mics (same as I connect it to the PC). The good news is : It works! I can record the mic sounds.
The bad news is, the two mono tracks are mushed together. If I use just one or both mics I always get a symmetrical stereo track.
Now, I don't want to be unfair. The Behringer requires that I install a driver in the PC. I'm assuming Audio Record app doesn't do the corresponding part in my Android smartphone.
So... The questions is: Is there a way to get separate tracks or do I need to wait until you add such functionality to AudioRecorder?
Thanks for your time and your beautiful app!
MIguel
Change the rate to something like low, lower, medium, high and higher. These can be easily understood by many users. Some people don't know what 48000Hz is.
I understand the need for uncompressed audio formats like WAV, but I suggest that you include lossy audio formats like MP3 in subsequent updates since it is the most popular one in the music world.
I think having audio trimmer functionality will be good so user can trim some noise from sound themselves.
Congrats to your app! May I ask if you'd consider an alternative download source for those without Google apps on their devices (and avoiding playstore)? You could e.g. use tags for your releases and attach the APK to it (many projects do so – and from there I could fetch it for my repo and keep it automatically up-to-date, so folks can use the F-Droid client to install and update it).
Speaking of F-Droid: having your app added to the official repo would certainly be great. But that would need a build flavor without Fabric and Crashlytics.
Thanks in advance for considering!
Thanks for the app, it works and looks good.
In favor of royalty free and efficient codec, would it be possible to implement opus?
It provides very good quality.
@Dimowner
It is helpful to only record system sound but not from mic. A setting to change this will be helpful.
Thanks

Audio Recorder is an open source application and every type of user can record their voice.
there is a manny feature in this application like rename share and replay etc.
Audio Recorder give us two format AAC or WAV with the help of this formate we can record our voice easily
The component I want to suggestion 2 feature is
1- Log in/Sign Up"
2- Upload Button
Audio Recorder is a simple application and the voice quality of the recording All the option are very easy and more benefits for users but I want to suggest some more feature benefits here
Everyone knows the Login/Sign Up" option is very important for every application with the help of this button users can make their own account for the application. When users will open their account a long time he will see all the history with the help of this application
sometimes users want to Save their audio recording files for a long time in the application. with the help of this option, users can save their files for a long time. when users will log in their account he will get all the upload audio recording files in the application.
The user can access their old history with the help of the login/Sign Up button you can Save all the recording files. The users can find easily files Which are uploaded in the option

The components (Features) I want to suggest is:
Audio Recorder has a very good function, you can record directly using this application. In terms of function, indeed this application has a very good function. I really appreciate the developer of this project.
On the one hand, I am very impressed with this application that looks very simple and cool. But I think, the Audio Recorder application still needs to be developed to make this application more interesting. There are so many other similar applications that have the same function, I think developers don't just rely on functionality, but also have to think about user experience, and a better and more interesting impression on them.
Therefore, I want to suggest some features for the Audio Recorder application. I hope my suggestions can be an additional idea for developers to make the Audio Recorder application more attractive.
Microphone adjustment
We recommend that the developer add this feature in the application settings section, and modify the section to make it easier for users. Press the button, make noise to determine the maximum gain factor, the developer must give the user the option to activate the device's auto gain control. The developer must add a calibration feature, and reset it in it, as well as mic level information after calibrating.
Recording volume (gain)
We recommend that developers add this feature in the application settings section. And giving the user the choice to change the recording volume, 0 db is the default value, and positive means the volume of the recording is louder. The developer must modify the section as best as possible, so that users can access it easily and quickly when changing the volume of recordings.
Several other recording file formats, such as mp3, 3GPP-AMR(low quality, save memory)
The developer must modify the format feature in the application settings section to add mp3 and 3GPP-AMR recording formats, and access to use it.
Below I will show examples of locations or illustrations if the features I recommend are implemented by the Developer.
Microphone adjustment
With the Microphone adjustment feature, users can calibrate the microphone, to get very satisfying and quality audio recordings. And that is a big advantage for users, they can also activate the device's auto gain control feature.
Recording volume (gain)
With the Recording volume (added) feature, users can change the recording volume, which is 0 db is the default value, and positive means the volume of the recording is louder. Users can record audio clearly, even though their device is in the pocket. The resulting audio recordings are very clear. And it was amazing and spoiled the users of this application.
Several other recording file formats, such as mp3, 3GPP-AMR(low quality, save memory)
After the developer adds mp3 and 3GPP-AMR formats, the available format options will be more complete in this application. Users can record audio using the low quality mp3 or 3GPP-AMR format and it will save memory on their device. This is perfect for those who have a small storage space.
To implement the features above, developers may need to make major improvements. And in my opinion, it doesn't matter because it will have a good effect later.
The features that I recommend are certainly very useful because it will improve the user experience later. And this will add value to the Audio Recorder application. And I hope, the Audio Recorder application developer will soon be able to implement this suggestion.
Hi,
Please support system-wide dark theme.
Your app requests the INTERNET
permission, but I couldn't figure out what it might be needed/used for. Maybe it could be removed?
I tried to record VOIP calls using your code, but I couldn't do so, I just tried your recorder code for recording WhatsApp recording of calls but recorder didn't start.
What are your suggestions for me to do this task and do you have any help/source code for this matter?
It seems you accidentally attached the debug APK at the latest tag. Could you please replace that with the release build? Thanks!
