问题
I have an audio track in AIFF format. I would like to open this audio file with Python, and import the amplitudes of the sound and perform some mathematical analysis such as Fourier Transform, etc.
- Is this possible in Python?
- Are there libraries or modules, which allow me to acquire an audio file?
Throughout my search, I have found scipy.io.wavfile, which works for WAV audio files.
- Are there other libraries to import audio files in Python?
- Is there something similar for AIFF files?
Obviously, I can convert the AIFF into a WAV file, but I would like to import the AIFF file directly, if possible.
As a side question: are there some more specific (by specific, I mean better than Python) programming languages to perform such kind of analysis and acquisition of audio files?
回答1:
Python comes with AIFF support as part of the standard library -- see the aifc module.
This module provides support for reading and writing AIFF and AIFF-C files. AIFF is Audio Interchange File Format, a format for storing digital audio samples in a file. AIFF-C is a newer version of the format that includes the ability to compress the audio data.
Depending on what your end goals are, you may be more productive using a tool like PureData that's designed just for working with audio and has things like reading audio files and performing ffts as primitives.

Yes, I also came across this problem using scipy.io.wavfile. I looked up the problem and see that Scikits might be interesting to get around this wave only solution.

As for Pure Data I use this a lot, but of course it does depend on what you wishing to do with your sound file...?
