Browser memory error for large audio files - files > 13 minutes

[aseem-heg]

Package version
6.0.0

Environment

• OS: Windows
• Browser Chrome

Describe the bug
When we record audio larger than 13 minutes on chrome browser - then click on stop which calls
final path = await record.stop();
We get this error shown below:

A clear and concise description of what the bug is.
Its a memory error - browser is running out of memory.

final record = AudioRecorder();
await record.start(const RecordConfig(), path: 'aFullPath/myFile.m4a');
final path = await record.stop(); 

Does the stop() command save audio in browser memory or disk ?

Add your record configuration RecordConfig(...)
await _audioRecorder.start(
const RecordConfig(encoder: AudioEncoder.wav),
path: 'audio.$fileExtension',
);

To Reproduce
Record audio larger than 13 minutes.
It works fine for smaller audio.

Expected behavior
Browser should not crash.

A clear and concise description of what you expected to happen.
Is there a way to record large audios without causing memory error ?
I want to upload the audio to a bucket using resumable URL.
Is there any example on how to do this on github ?

I am also trying streaming - but I could not find complete example on streaming using this package on Github.
Looking for details like how to listen to the stream, How to stop the stream, How to get chunks from streaming , how to upload them to a resumable URL on gcs etc..

Thanks for the report. You're right. PCM and WAVE are filled into memory. I don't if there is a better solution to this. I'll dig into it.
For streaming, you can check in the example project for a foo process.

Unfortunately, there is no good solution about this for web platform at this time.
There's an experimental showSaveFilePicker but this is not widely supported...

Anyway, I'll try to implement this in the plugin.

HI， this issues only happend in wav or pcm format ? AAC format have this issue or not ?
And have you try any other packages for recording voice in web browser ?
Thank you
