Title: Re: Recording compressed audio file
Hi,
We are using the 1.2 version of Speakhere application.
In the initWithURL method of the AudioRecorder we found ,
// Specify the recording format. Options are:
//
// kAudioFormatLinearPCM
// kAudioFormatAppleLossless
// kAudioFormatAppleIMA4
// kAudioFormatiLBC
// kAudioFormatULaw
// kAudioFormatALaw //
// When targeting the Simulator, SpeakHere uses linear PCM regardless of the format
// specified here. See the setupAudioFormat: method in this file.
[self setupAudioFormat: kAudioFormatLinearPCM];
Is it possible to use recording format other than Linear PCM ?
Thank you.

Hi,
I use SpeakHere application which record only the uncompressed audio.
I need to record compressed audio file. How it can be done ?
I got the properties of a compressed audio file
Like
audioFormat.mFormatFlags = 2
audioFormat.mFramesPerPacket = 1024;
audioFormat.mBitsPerChannel = 0;
audioFormat.mBytesPerPacket = 0;
audioFormat.mBytesPerFrame = 0;
So I tried to record the new file by setting these properties. But I can’t record it.
Thank you in advance.
