Summary

Description
English: A recording of "The North Wind and the Sun" prepared to compare the performance of w:Lyra (codec) with other codecs. This version uses Speex at 3 kbps and an 8 kHz (narrowband) sample rate.

Detailed description of how this file was made:

OS: Ubuntu 22.04 x86_64

Processed with ffmpeg 4.4.2-0ubuntu0.22.04.1 and speexenc 1.2rc1, which was packaged in Ubuntu as speex and libspeex versions 1.2~rc1.2-1.1ubuntu3. Resampled to 8kHz with ffmpeg because Speex uses narrowband at low bitrates:

ffmpeg -i north-wind-orig.ogg -ar 8000 north-wind-8khz.wav

Then compressed with this command:

speexenc --bitrate 3000 --comp 10 north-wind-8khz.wav north-wind-speex-3kbps.spx

Finally, converted to flac for upload.
