Add Bass or Treble to a ouput from a Steraming audio data input

[ptiriv]

Hi,

I have a streaming input from a radio, I would like to add Bass or Treble to this audio data before to put it into my queuebuffer (which play the audio data)

I have a method to handle audio packets

PHP Code:

    - (void)handleAudioPackets:(const void *)inInputData
    numberBytes:(UInt32)inNumberBytes
    numberPackets:(UInt32)inNumberPackets
    packetDescriptions:(AudioStreamPacketDescription *)inPacketDescriptions;
    {

    ....
            
    AudioQueueBufferRef fillBuf = audioQueueBuffer[fillBufferIndex];

    // Here I think I have to add Bass or Treble to inInputData
    memcpy((char*)fillBuf->mAudioData + bytesFilled, (const char*)inInputData  + packetOffset, packetSize);
        
    ....
    } 


The streaming flux is mp3 44100.

if somebody have an idea...

thx
