Audio file spectral analysis
Project description
specky
specky is a collection of easy-to-use Python and command-line tools for analyzing audio files.
specky-show filename.mp3 # shows the wave spectrum of the audio file
specky-check filename.mp3 # checks if the audio file is worse than it pretends to be
See -h for their respective command-line arguments.
The quality of MP3 files is typically determined by their bitrate. For audio files, 128 kbps (kilobit per second) is considered low quality, 320 kbps is considered high quality. It is of course possible to re-encode a low-quality MP3 with a higher bitrate or even a WAV file. specky can help singling out those foul eggs.
Here is the specky-show output of a sample
file (only first
channel shown):
 |
 |
 |
|---|---|---|
| Full-quality WAV | 320 kbps MP3 | 256 kbps MP3 |
 |
 |
 |
| 192 kbps MP3 | 128 kbps MP3 | 64 kbps MP3 |
 |
|
 |
| 96 kbps MP3 | 64 kbps MP3 | 32 kbps MP3 |
