This version includes a new AudioStreamer type. Note that this is a beta version (for this type only). The purpose of AudioStreamer is to make it simple to stream audio from the microphone and to the speakers. Internally it is based on AudioTrack and AudioRecord. Next week I plan to create an exam

It will be simpler to use B4XSerializator and send a custom type with the audio data and any other data you want to send.

AudioStreamer is a B4A only library. You can try to use jAudioRecord to capture the audio. I do not know whether it is compatible with Raspberry Pi.

The AudioStreamer() liberary offers what you are looking for. it takes the Microphone recording and buffers the samples in a Byte()-Array. Then you will need the ByteConverter()-Library to convert them into Short()-Arrays. The ByteConverter.LittleEndian must set to true. In combination with a Time

For streaming you will probably get better performance with the AudioStreamer object from the Audio Library: https://www.b4x.-library-v1-5-new-audiostreamer-object.30550/

The Audiostreamer Lib is designer for playing a stream of audio. If you are generating the audio on the fly It would make more sense to use the AudioTrack Object directly. There is a library https://www.b4x..14007/ Although the audio streamer uses Audiotrack to play the sound, not all of the avai

Sorry I dont understand is the audiostreamer is a wrapper for android audiotrack ? Seems like that for the recording behaviour to me Because in other ide that uses audiotrack that was a similar case and dividing the buffer seems was solve to all issues on other devices BUFFSIZE := TJAudioRecord.Jav

Use AudioStreamer in Audio library you can generate the two signals and put in left/right channels in a stereo wave and play it. I remeber there is a post on the forum exactly discussing about this but I forget the keyword for searching.

For this it is better to user AudioRecord made by steve, record raw PCM audio in a buffer and check raw audio data in the buffer instead of in a file. I believe AudioStreamer is the same and convinient as it has a callback event mentioned by JohnC to avoid using the threading lib. If it is not in re
