channels error in func saveWave

[lomizandtyd]

def saveWave(filename, data, samplerate, verbose=False) :
    if verbose: print("Saving wave file:",filename)
    blockSize = 512
    channels, frames = data.shape                             # data.shape -> (channels, frames)
    fullblocks = frames // blockSize
    lastBlockSize = frames % blockSize
    with WaveWriter(filename, channels=channels, samplerate=samplerate) as w :
        for i in range(fullblocks) :
            w.write(data[blockSize*i:blockSize*(i+1)])    # blockSize for 'frames'  dimension, not for 'channels' dimension..
        if lastBlockSize :
            w.write(data[fullblocks*blockSize:])

in line w.write(data[blockSize*i:blockSize*(i+1)])

it may be w.write(data[:, blockSize*i : blockSize*(i+1)])

Sure it works for me, so i guess you are facing a diferent use case with different data layout. Which one? 2017-09-18 3:32 GMT+02:00 kujikuji <notifications@github.com>:
