new audio format

[AnthonyKoueik]

can this app support other formats, like mp3, AAC ... ?

Hi @AnthonyKoueik,

You're lucky! I've made a lib for that yesterday. Please check AndroidAudioConverter.

After the recording finish, you can convert WAV to AAC, MP3, M4A, WMA and FLAC:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            // Great! User has recorded and saved the audio file
            // Now you can convert it
            AndroidAudioConverter.with(MyActivity.this)
                .setFile(myWavFile) 
                .setFormat(AndroidAudioConverter.AudioFormat.MP3)
                .setCallback(callback)
                .convert();
        } else if (resultCode == RESULT_CANCELED) {
            // Oops! User has canceled the recording
        }
    }
}

Please let me know if this solve your problem.

that's amazing, but i want to ask if this affect the size?
like aac format files a usually small and fine quality.
anyway i will try it out now.
awesome work

[adrielcafe]

Yes, the size reduce a lot with AAC, MP3, M4A and WMA formats.
I've made a quick test: an WAV file with 10s has ~500KB, while any format above has less than 60KB.

⚠️ Because I've made AndroidAudioConverter with FFmpeg lib my lib has ~20MB 😞 . I'm looking for alternatives to reduce the lib size.

[AnthonyKoueik]

I didn't read your Audio Recorder code, can't I change it to aac output ?

[adrielcafe]

I'm using OmRecorder lib to record audio. Currently it does't support other formats.

how can i get the time of my audio file

[Mathias8405]

The library loads just fine for me, but I can not get it to convert files. All converts failed. I am not sure if it's because of the new scoped storage method for apps with api 29 and up or what the issue is. ActivityForResult is depreciated, and with the new method it still doesn't work. Hey Adrielcafe, will you please give us an update that works with Android 12 api 32, and the new ActivityForResult launcher method, and with the new scoped storage. Thanks!
