spectro is a collection of easy-to-use Python and command-line tools for analyzing audio

files. Install from [PyPi](https://pypi.org/project/spectro/) with

```

pip install spectro

```

and use with

```bash

spectro show filename.mp3                # shows the wave spectrum of the audio file

spectro check {dirname or 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. spectro can help singling out those foul eggs.

Here is the `spectro show` output of a [sample

file](https://nschloe.github.io/spectro/Yamaha-V50-Ride-Pattern-120bpm.wav) (only first

channel shown):
