Myujth

I need to write the output file in external storage with applied effects but don't know how to do this. Any help will be highly appreciated to make audio output mp3 or mp4 file with effects. I have successfully done the pitch change of real time, I have used some code of write file to external storage but the file generated is only 0 bytes and corrupted.I have used below code

 const char *output1 = "/storage/emulated/0/Music/123456.mp3";
const char *openError = decoder->open(input, false, 0, 0, 0);
if (openError) 
 delete decoder;
 return false;
;

FILE *fd = createWAV(output1, decoder->samplerate, 2);
if (!fd) 
 delete decoder;
 return false;
;

float effectMix = 0.5f;
SuperpoweredFX *effect = NULL;
if (effectId == 0) 
 player->setPitchShift(10);
 effect = new SuperpoweredEcho(decoder->samplerate);
 ((SuperpoweredEcho *) effect)->setMix(effectMix);
 else if (effectId == 1) 
 effect = new SuperpoweredReverb(decoder->samplerate);
 ((SuperpoweredReverb *) effect)->setMix(effectMix);


if (effect == NULL) 
 delete decoder;
 return false;


effect->enable(true);
short int *intBuffer = (short int *) malloc(
decoder->samplesPerFrame * 2 * sizeof(short int) + 16384);
float *floatBuffer = (float *) malloc(decoder->samplesPerFrame * 2 * sizeof(float) + 1024);
unsigned int samplesDecoded;
while (true) 
 samplesDecoded = decoder->samplesPerFrame;
 if (decoder->decode(intBuffer, &samplesDecoded) == SUPERPOWEREDDECODER_ERROR) 
 break;
 
 if (samplesDecoded < 1) 
 break;
 

 SuperpoweredShortIntToFloat(intBuffer, floatBuffer, samplesDecoded);

 effect->process(floatBuffer, floatBuffer, samplesDecoded);

 // Convert the PCM samples from 32-bit floating point to 16-bit integer.
 SuperpoweredFloatToShortInt(floatBuffer, intBuffer, samplesDecoded);



fwrite(intBuffer, 1, samplesDecoded * 4, fd);
closeWAV(fd);
delete decoder;
delete effect;
free(intBuffer);
free(floatBuffer);
return true;

Please help with this code.

I have error like below.

error log shows some firebase issues but one major issue found in the code is you have put

fwrite(intBuffer, 1, samplesDecoded * 4, fd);

outside the while loop.

It should be inside it as the intBuffer gets filled with chunk of audio data in each iteration.
