Question

In Python I have this function=
Def get_audio(): Fs, data = Wavfile.read(“song file path”) Left_channel = data.T[0] Return (left_channel, fs)
In line 2 I know the left channel of the song is taken (half the data) but how does data.T[0] do this? In Python I have this function=
Def get_audio(): Fs, data = Wavfile.read(“song file path”) Left_channel = data.T[0] Return (left_channel, fs)
In line 2 I know the left channel of the song is taken (half the data) but how does data.T[0] do this?

In line 2 I know the left channel of the song is taken (half the data) but how does data.T[0] do this?

Explanation / Answer

Answer:

Beacuse there are two channels in wav audio files : left channel and right channel and the Wavfile.read() function returns a numpy array. This array contains the two channels. Here in above code 'data' will receive that array. T[0] will contain the left channel and T[1] contain the right channel.

You can also select the left channel like this : Left_channel=data[:,0]

Thankyou
