recording in float with AVAudioRecorder

Hi,

When I record using AVAudioRecorder and the following parameters, I get 32bit samples (what I want) but they are not floats. Does anybody know what happens ?

NSDictionary *recordSettings =

[NSDictionary dictionaryWithObjectsAndKeys:

[NSNumber numberWithInt: kAudioFormatLinearPCM], AVFormatIDKey,

[NSNumber numberWithFloat: 44100.0], AVSampleRateKey,

[NSNumber numberWithInt: 1], AVNumberOfChannelsKey,

[NSNumber numberWithInt: 32], AVLinearPCMBitDepthKey,

[NSNumber numberWithBool:YES], AVLinearPCMIsFloatKey,

nil];

Vincent
