In SASAudioRecordExample, which uses the library as an aar.
On first screen, have 2 buttons:
Create Media/Audio Recorder instance

For Media Recorder Instance, additional parameters available for access:

1. Bit-rate

Reproducible steps:
Press Initialize
Press Set Path
Press Play Recording
App crashes

Need to check if same steps cause crash in media recorder

Use 200ms default value

Which function is supposed to be called when autostop mode is enabled?

Code currently calls lower one. For what case is the upper one called for then?

If all buttons from top pressed sequentially (sunny day scenario) on pressing Stop Recording after Start recorder puts recorder in invalid state.

Have not managed to record at all due to this.

Modes:

1. Autostop - Disabled, Audio Recording Duration is specified when intantiating the recorder object
   Once recorder has started, it can be stopped by any of the following events

• manually stopping the recorder
• automatically stops when Audio Recording Duration is exceeded

2. Autostop - Enabled, Audio Recording Duration is specified when intantiating the recorder object
   Once recorder has started, it can be stopped by any of the following events

• manually stopping the recorder
• automatically stops when Audio Recording Duration is exceeded
• Autostop logic triggers stopping of recorder (Autostop logic identifies that user has started speaking and then stopped speaking)

Check MediaRecorder settings from HappyLingo. Quality is poor when recording here. Mostly bitrate is the issue. Also for MediaRecorder use the correct file extension (mp4) instead of .wav

Processing logic needs to know if it has already identified that the person has started speaking so that it can check if person has stopped speaking. If this state is not known, entire energy buffer will need to be processed to identify if the user has both started speaking and stopped speaking and processing time will vary based on how long the buffer is.

If the state of user having started speaking is known, one can just look back for a fixed duration to identify if the user has stopped speaking. Processing time will be constant in this case.

Open App
Tap Create Recorder Instance
Press close button

Why does the SAS state show: "Invalid" on creating recorder. It should show "Initial"?

If ARL is not initialized and if you try to set path, you get a toast indicating "Failed to set audio path". However, pressing on any of the other buttons "Prepare/Start Recording/Stop Recording" does not show that "ARL state: Invalid State.

Explanation: If already ARL is in invalid state, the ARL state is not updated.

No ready made function available like MediaRecorder here

Even though headphone is not connected
