我需要使用应用效果将输出文件写入外部存储，但不知道如何执行此操作。任何帮助都将非常感谢您制作带有效果的音频输出 mp3 或 mp4 文件。我已经成功地完成了实时音高变化，我已经使用了一些将文件写入外部存储的代码，但生成的文件只有 0 字节并且已损坏。我使用了以下代码
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;
请帮助使用此代码。
我有如下错误。
