A script to check a collection of audio recordings for 1) expected files, 2) expected specification, and 3) provenance. |
| Detailed description |
audio_audit: Audit a series of Wave files.
OPTIONS:
-h Show this message.
-i Input path (mandatory).
-f Perform fingerprint verification of Master/Listening pairs.
-v Display version.
This is a simple bash script which uses two main tools:
- BWF MetaEdit: for extracting file-specific metadata (sample rate, sample bit-rate).
- jHears: for audio fingerprinting (which also relies on SoX). Both client and server software are required.
It is used to check a series of paired Wave files (a Master and Listening copy) against certain criteria:
# That for each Master there is a corresponding listening copy.# That each Wave file has the correct sample rate and sample bit-rate.# Optionally, that each Listening copy has a sufficiently similar audio fingerprint to that of the Master.

| Group Evaluation Notes |
- Fingerprinting tested on sample collection but mixed results at matching pair. Masters and service files may not be close enough for fingerprinting to work
- Further investigation needed on results and tweaking the fingerprinting parameters
- Would be interesting to try this on other
- Would other tools/techniques work better. Eg. AudioScout? http://freshmeat.net/projects/audioscout or libofa
- Potentially very useful to issue champion, especially spec checking
- Could check on submission
- Organisation could quite easily utilise the script
- If wrapped as windows usable tool could be used by those generating the recordings
- Potential to investigate further metadata extraction
- Potential to take results away, trial it, generate more requirements and then bring to London AQuA event
- Might be able to bring in additional sound expertise for London (BL Sound and Vision?)
