audiostream's Introduction

Kivy

Kivy is an open-source Python framework for developing GUI apps that work cross-platform, including desktop, mobile and embedded platforms.

The aim is to allow for quick and easy interaction design and rapid prototyping whilst making your code reusable and deployable: Innovative user interfaces made easy.

Kivy is written in Python and Cython and is built on OpenGL ES 2.0. It supports various input devices and has an extensive (and extensible) widget library. With the same codebase, you can target Windows, macOS, Linux (including Raspberry Pi OS), Android, and iOS. All Kivy widgets are built with multitouch support.

Kivy is MIT licensed, actively developed by a great community and is supported by many projects managed by the Kivy Organization.

Installation, Documentation and Examples

Extensive installation instructions as well as tutorials and general documentation, including an API reference, can be found at https://www.kivy.org/docs. A PDF version is also available.

Kivy ships with many examples which can be found in the examples folder.

Support

Are you having trouble using the Kivy framework, or any of its related projects? Is there an error you don’t understand? Are you trying to figure out how to use it? We have volunteers who can help!

JNI RegisterNatives called with pending exception java.lang.ClassNotFoundException: Didn't find class "org.audiostream.AudioIn"

Hi, I've created a Google colab so you can simply recreate the error.

My code is:

from audiostream import get_input
from android.permissions import request_permissions, Permission
request_permissions([Permission.RECORD_AUDIO])
def mic_callback(buf):
    print("got", len(buf))
print("KEYWORD_TO_SEARCH_IN_ADB_LOGCAT")
mic = get_input(callback=mic_callback)

but in adb logcat I read:

02-25 10:53:48.359 1299 1568 F org.test.myapp: java_vm_ext.cc:570] JNI DETECTED ERROR IN APPLICATION: JNI RegisterNatives called with pending exception java.lang.ClassNotFoundException: Didn't find class "org.audiostream.AudioIn" on path: DexPathList[[zip file "/data/app/org.test.myapp-VZcDiTQAVptYQlU1RG8YjQ==/base.apk"],nativeLibraryDirectories=[/data/app/org.test.myapp-VZcDiTQAVptYQlU1RG8YjQ==/lib/arm, /data/app/org.test.myapp-VZcDiTQAVptYQlU1RG8YjQ==/base.apk!/lib/armeabi-v7a, /system/lib, /system/product/lib]]

and then, the application crashed.

Thanks for your help. I believe that if we create a working google colab it can also be integrated into the homepage to be used as a starting point.

Buffersize is required for get_input to work

audiostream.get_input doesn't work unless you specify a valid buffersize. What buffersize to use is some sort of magic from tito.

Get_bytes call too many times

Hello ,
Before anything thanks for the works done on this AudioStream module.

I have an issue that i can't find a solution. I have a python Kivy app who use the Threadsource method. so i cut my sound in step

1 step = 1/4 BPM = (samplerate 15/BPM) samples so it should call the function Get_bytes 4BPM but it's call way more so my sound is read very fast can you help me ?

Thanks in advance

ImportError: cannot import name 'get_input' from 'audiostream' (unknown location)

I installed audiostream on my mac with python 3.9. When I try your example of recording from microphone at line

from audiostream import get_input
I get the error of:

ImportError: cannot import name 'get_input' from 'audiostream' (unknown location)

Any ideas?

ModuleNotFoundError: No module named 'audiostream.core' Tried on python3 and python2

AudioInput on mac

I used the iOS code to add an AudioInput class for Mac. The changes are here:

https://github.com/pbouda/audiostream

I would send a pull request if you think it makes sense to integrate the code. Here is what I did:

I copied the iOS code and adapted the classes so that it works on Mac. The main difference is the code to find the default audio device.
I had to add GIL handling to the C++ code (see for example the callback), otherwise the code crashed after calling the C++ callback.
Some minor changes in setup.py to compile on "darwin" platforms. I added the include path to the brew SDL.
I added an example that writes a wave file based on the input, to see if my code works. Maybe not necessary for a pull request...?

https://github.com/pbouda/audiostream/blob/master/examples/record_mac.py

Probably some code could be shared between iOS and Mac OS, but I would leave that to later work...

sound is crackled

I'm making a sound classification android app by using kivy and audiostream module.

But when I recorded the sound from outside through mic, the sound is crackled (The sound is kind of cut off).
I change the devices and tried other things but still sound is unclear.
Do you how to make the sound smoothly? (I checked the document but there was no function for that.)
or is there anyway to solve it?

Thank you:)

build Termux

can not be Build under the Termux does not see the android platforms. can't work with $PREFIX.
does not see SDL2.

ThreadSource error

When I try to run the sinslider example I get this error:

I/python (13506): ImportError: cannot import name ThreadSource

Any workaround for this?

What can be the problem here? I reinstalled Python few times - tried with different versions. It didn't help, though..
I would appreciate any suggestion, hint, idea.
thank you.

Issue recording audio after outputting audio - iOS

There appears to be an issue whereby mic.poll() does not call the callback function of 'get_input(callback = callbackFunction, rate = rate, buffersize = buffersize) after using the speaker's on my iPhone to output audio.

My code works fine recording audio with no previous activity, but if I use the audiostream's AudioOutput module or Kivy's SoundLoader module and try to record audio again using get_input, then mic.poll() fails and no buffer data is sent to the callback function of get_input. I imagine this issue is to do with how the phone is re-configured when it's speakers are used, as, if I do not output any audio, I can record audio using audiostream an infinite number of times.

Here is my code to record the audio:

def __init__(self, **kw):
    super().__init__(**kw)
    self.samples_per_second = 60 # variables which stores the number of audio samples recorded per second
    self.audioData = [] # creates a list to store the audio bytes recorded
    import sys
    importlib.reload(sys.modules['audiostream']) # reloads the audiostream module - thought this might solve the problem; it doesn't!!
    self.mic = get_input(callback=self.micCallback, rate=8000, source='default', buffersize=2048) # initialises the method get_input from the module 'audiostream' with the properties required to ensure the audio is recorded correctly

def micCallback(self, buffer):
    # method which is called by the method 'get_input' to store recorded audio data (each buffer of audio samples)
    self.audioData.append(buffer) # appends each buffer (chunk of audio data) to variable 'self.audioData'

def start(self):
    # method which begins the process of recording the audio data
    self.mic.start() # starts the method 'self.mic' recording audio data
    Clock.schedule_interval(self.readChunk, 1 / self.samples_per_second) # calls the method 'self.readChunk' to read and store each audio buffer (2048 samples) 60 times per second

def readChunk(self, sampleRate):
    # method which coordinates the reading and storing of the bytes from each buffer of audio data (which is a chunk of 2048 samples)
    self.mic.poll()  # calls 'get_input(callback=self.mic_callback, source='mic', buffersize=2048)' to read the byte content. This byte content is then dispatched to the callback method 'self.micCallback'

def stop(self):
    # method which terminates and saves the audio recording when the recording has been successful
    Clock.unschedule(self.readChunk) # un-schedules the Clock's rythmic execution of the 'self.readChunk' callback
    self.mic.stop() # stops recording audio
    return self.audioData

Here is the code I have used to output audio after using the above code to record audio:

messageFile_voice = SoundLoader.load("filename.wav")
messageFile_voice.play()

Can't record

Running this bit of code:

def mic_callback(buf):
print 'got', len(buf)
frames.append(buf)
print ('size of frames: ' + len(frames))

def bcallback(instance):

    mic = get_input(callback=mic_callback, source='mic')
    mic.start()

    #mic.poll()
    time.sleep(5)

    mic.stop()

class MyApp(App):
def build(self):

    btn1 = Button(text='Audio Record')
    btn1.bind(on_press=bcallback)

    return btn1

if name == 'main':
MyApp().run()

and using logcat I can see that mic_callback isn't working since there isn't any print on logcat.

I've tried to change source to 'default' also, but doesn't work either.

Is it possible to use audiostream in service?

I'm building some sound generating app for android which uses audiostream module and it works fine in main app, but not in service. When i start service it crashes with error message:
SDL_Init: Application didn't initialize properly, did you include SDL_main.h in the file containing your main() function?

This message is returned by SDL, and it means SDL_SetMainReady is False, which sets to True on main app init. So SDL must be initialized again, but for service? If yes, please advise me how to do it.

AudioOutput channels remains at value 2

Cannot set AudioOutput channels at value 1

Test program:

from kivy.core.audio import SoundLoader
from audiostream import get_output
sound = SoundLoader.load('sounds/kit1/clap.wav')
if sound:
print("Sound found at %s" % sound.source)
print("Sound is %.3f seconds" % sound.length)
sound.play()
stream = get_output(channels=1, rate=44100, buffersize=1024)
print(type(stream))

Output:

Sound found at C:...\sounds\kit1\clap.wav
Sound is 0.522 seconds
AudioOutput ask for 44100 1
AudioOutput got 44100 2

if
stream = get_output(channels=1, rate=22050, buffersize=512)
then
AudioOutput ask for 22050 1
AudioOutput got 22050 2

Building audiostream for Android with buildozer complains about missing files

I'm building an Android app with Kivy, the user interface builds and works great on Android, and I'm now trying to add audiostream to the project so I can record audio from the phone's microphone.

I installed audiostream with pip install git+https://github.com/kivy/audiostream and it built fine.

Then I added the same thing to my buildozer.spec as such:

requirements = python3,kivy==2.0.0,git+https://github.com/kivy/audiostream.git

However when building for Android, the following error happens:

Using legacy 'setup.py install' for audiostream, since package 'wheel' is not installed.

I've tried building audiostream with and without the USE_SDL2 flag, doing full cleans in between, but I get the same error every time.

Has anyone gotten audiostream working with buildozer on Android? How did you manage it?

Add project infrastructure

audiostream needs a lot of project infrastructure:

There is no pypi package.
There is no documentation.
There is no information about platforms supported.
There are zero unit tests.
There are no CI actions.

fail to install

Have installed Kivy, and now trying to install Audiostream, but get an error:

>pip3 install git+https://github.com/kivy/audiostream.git
Collecting git+https://github.com/kivy/audiostream.git
  Cloning https://github.com/kivy/audiostream.git to /tmp/pip-uhs2_2ti-build

                                    ^

Why this could happened?
I have Cython v0.26

>pip3 list | grep Cython
Cython (0.26)

changing number of channels causes a frequency change in SineSource

Generating a sine wave as shown in the first blocks of the sine example in
http://audiostream.readthedocs.org/en/latest/#examples
and changing the number of channels from 1 to 2 or from 2 to 1 changes the frequency (half and double, respectively).

I tried to dive into the code and think it is because the AudioSample class and the AudioOutput class (from audiostream.core) can have different channel settings (variables .channels and .channel, respectively).

Wrong Platform

get_input(callback=callback_mic)

gives me wrong platform, is there any documentation about this module?

Python3 support

Hello,

It seems that audiostream is not yet ready for python3. I tried to fix a few errors but then my knowledge found its limits.

In sources directory, two files have problems with arrays (waves.pyx and puredata.pyx):
search for lines like that :
buf = array('h', '\x00' * self.chunksize)
It seems that this is easy to fix by just adding a 'b':
buf = array('h', b'\x00' * self.chunksize)
There are a few iterations only of them.
Then in waves.pyx there are a few uses of "next" that is no more valid in python3. I tried to change them with the new syntax but it was not sufficient or proper I am afraid.

Can i play local files?

SoundLoader is for some reasons not working on android, can i use audiostream to play mp3 audio from local files? How can i do that?

cant compile for android

Just discovered the audiostream package, and it's awesome. Sadly can't build for Android (at least from OS X...) log below.

ImportError: dlopen failed: cannot locate symbol "SDL_ANDROID_GetJNIEnv"

Hi
I tried the record_mac.py example provided. I also tried this code. The build process is fine and I have added audiostream to my requirements in buildozer.spec.
The problem I am facing is that the app crashes on the android device and logcat output is giving me the error.

Cant install this module on windows 11

I am installing the package inside a virtual environment using the pipenv tool.

My error looks like this.

iOS audio signal processing - how to turn off?

I have built an audio spectrum analyser using audiostream and kivy, this is working well. However, iOS does some signal processing by default and has a low cut filter on all microphone input. How can I by-pass this processing?
I understand that I need to set the AudioSession category and measurement mode but I am unsure how to approach this. Can someone please help or point me in the right direction?
