[~filmaj]yes I have a signed Apache ICLA. I got an e-mail from Craig L Russel saying
"With this message, the Cordova PMC has been notified that your ICLA has been filed."
So please ask the Cordova PMC (because I don't know who this is:-)

> I get “Failed to initialize AVAudioRecorder: (null)” in the error callback of the startRecordingAudio() exec API.
> I see that the AVAudioPlayer settings in CDVAudio.m are
> {code}
> NSDictionary *audioSettings = @{AVFormatIDKey: @(kAudioFormatMPEG4AAC),
>                                             AVSampleRateKey: @(44100),
>                                             AVNumberOfChannelsKey: @(1),
>                                             AVEncoderAudioQualityKey: @(AVAudioQualityMedium)
>                                             };
> {code}
> This is IMHO the reason it doesn’t work. Either one uses the .m4a extension with {{kAudioFormatMPEG4AAC}} or
> .wav with the {{kAudioFormatLinearPCM}} key (the IOS docs are very unclear about which file extensions are actually supported)
> The plugin enforces “wav” but the settings enforce the MPEG4AAC encoder.
> Using the attached simple patch and using .m4a at the JS side solves the problem and records on my iPod touch IOS 8.x.
> I stumbled also across https://github.com/remoorejr/cordova-plugin-media-with-compression where the exchange wav->m4a is done too.
> Strangely I can’t find much problems reported on stackoverflow, but this one seems to cover it
> http://stackoverflow.com/questions/12244111/failed-to-initialize-avaudiorecorder-null
> The last poster seem to indicate that the problem sneaked in in IOS 8 (previously it was probably possible to record to a .wav file but with AAC content).
> Looking at the recordAudio() test for the plugin in tests/tests.js I can’t see that potential errors are actually causing the test to fail: they are just logged with console.log , so this may explain why the problem has not been detected by the tests.
