scipy.io.wavfile.write¶
- scipy.io.wavfile.write(filename, rate, data)[source]¶
Write a numpy array as a WAV file
Parameters: filename : string or open file handle
Output wav file
rate : int
The sample rate (in samples/sec).
data : ndarray
A 1-D or 2-D numpy array of either integer or float data-type.
Notes
- The file can be an open file or a filename.
- Writes a simple uncompressed WAV file.
- The bits-per-sample will be determined by the data-type.
- To write multiple-channels, use a 2-D array of shape (Nsamples, Nchannels).
