The method used is linear or logarithmic sweeps and deconvolution.
The object of Aliki is to make IR measurement easy. It has a graphical
user interface, and can work with either ALSA directly or via JACK (it
will also work without any audio interface for post-processing files).
You will get a good idea of Aliki by reading the manual.
Main functions are:
- Generating sweep files.
- Performing the actual measurement (up to 8 channels).
- Deconvolution to get the IR.
- Simple editing on the IR to prepare it for use.
This is only a small subset of what it's planned to offer in the
The measured IR can be exported to WAV files.
Sox will convert this to the raw format expected by DRC.
Aliki is not designed to replace DRC, but should complement it
by providing an easy-to-use measurement solution. Some DRC-like
functionality will be included in the future, but nothing of
the sophistication of Denis Sbragion's magnificent software.
Lascia la spina, cogli la rosa.
