b2btest audio - Audio file plugin for b2btest
============================================================

This package adds audio file support to b2btest.
b2btest is a tool to automate tests that compare results
to some previous ones, and this plugin,
is helpful to compare audiofiles in a sensible way.
See [b2btest README](https://github.com/vokimon/back2back)
for a deeper discussion on why you should avoid back-to-back testing,
although sometimes it is the lesser evil way to proceed.
This plugin handles audiofiles specially in several ways:
- Instead of doing a text or byte difference, it interprets the audio contents and compares them sample by sample.
- It considers two outputs to be different if:
- Metadata differs
- Sample-by-sample differs relative to the audio level
- In the case of differences, it generates a diff audio by substracting both waves sample by sample.
By means of `python-wavefile`, it supports floating point samples, and multichannel waves.
How to install
--------------
Just use:
```bash
$ pip install b2btest_audio
```
Dependencies
------------
This plugin requires the [wavefile] module,
which in turn requires having [libsndfile] library installed in your system.
[wavefile]: https://github.com/vokimon/python-wavefile
[libsndfile]: http://www.mega-nerd.com/libsndfile/
Back2Back testing of cli programs
---------------------------------
When you are testing back-to-back the output of a command line,
you define a yaml file like this (name it b2bcases.yaml).
```yaml
#!/usr/bin/env back2back
datapath: "b2bdata" # Point it to the directory containing your reference data
testcases:
Generate1KHzSine:
command: sox -n /tmp/sine.wav synth 1.0 sine 1000.0
outputs:
- /tmp/sine.wav
```
Ouputs with supported audio file extension will be recognize
and this plugin diff will be used for them.
See [b2btest] documentation on how to use this file.
Command line tool
-----------------
The package also provides a `diffaudio` CLI tool to generate the audio difference
Change log

- Fix: entry points for xml and audio plugins
- Just markdown README
### b2btest 1.3.1
- Updated README
### b2btest 1.3
- Avoid larg diffs by telling just the generated file with the failed results
- Fix unicode problems in certain python versions
- Using older lxml versions for python<3.5
### b2btest 1.2
- CLI: Fix: only the first output was actually checked
- Plugin based type sensitive diff
- Specific diff for XML
- XML and Audio diffing now are extras
- 'extensions' key in yaml testcases to associate custom file extensions to a diff plugin
### b2btest 1.1
- Unit test like usage for back-to-back test Python code instead of command line programs.
- New commandline tool `back2back` that takes a yaml file with the test cases definitions.
### b2btest 1.0
- First github version
- (There were previous unpublished versions)
