Audio Quality Assessment

Survey app for tracking audio quality.

If you have 10 minutes you can take it here: audio.nicco.io

Frontend

Written with Svelte & Sapper.

Sources

Music is taken from high res FLACs (44.1k 16bit) and converted down to 64, 128, 256 and 329kbps mp3s using ffmpeg by a python script.

Backend

Backend is a simple route in sapper that saves data to NeDB protected by recapcha for human only interactions.

To get the data you can simply call /api/collect

Convert & Prepare Tracks

Place as many .flac files in the audio/original folder and inside of the audio/original folder run python3 conver.py. This will convert the files and put them into static/converted along with a data.json which makes the files discoverable. If a track already is converted it will be skipped
