MIDI isn't an "audio" format. You can work with MIDI Files using
functions in AudioToolbox/MusicPlayer.h...
The error from AAC is 'fmt?'. What is "inputFormat"?

Hi,
I am trying to convert few file formats to WAVE file format. The
code works fine for MP3 and AIFF file formats. But, when i use the
MIDI format, i am not able to open the audiofile itself. And, when i
use AAC audio files, the converter throws an error. Error code is
1718449215.
Code:
OSStatus err = AudioConverterNew (&inputFormat, &outputFormat,
&converter);
where, inputFormat, outputFormat -> AudioStreamBasicDescription and
converter -> AudioConverterRef. This err = 1718449215
I am setting the following values for the outputFormat. This is the
same format that i have used with MP3 and AIFF files.
mBitsPerChannel - 16
mBytesPerFrame - 4
mBytesPerPacket - 4
mChannelsPerFrame - 2
mFormatFlags - 12 ( kLinearPCMFormatFlagIsSignedInteger |
kLinearPCMFormatFlagIsPacked )
mFormatID - 1819304813 ( kAudioFormatLinearPCM )
mFramesPerPacket - 1
mReserved - 0
mSampleRate - 44100
Please tell me where i have gone wrong and if i needed to add
something else along with this.
