For THIS kind of continuous auto-logging, we're using a low-cost program called "Total Recorder"

totalrecorder.com

It runs 24/7/365, recording in 8 bit uncompressed WAV at 8Khz. It provides acceptable audio quality for auditing and verifying what aired and when (or if it didn't).

It runs on a special PC in the studio and automatically saves the audio files every half hour to a USB disk drive. I chose WAV instead of MP3 because even at this low sample rate and 8 bits, it still sounds MUCH better than the low-rate MP3 did, though.

Not sure about the auto-purge... but there is a program called "Belvedere" that's freeware, and can be configured to auto-delete aged files in folders you specify.

Hello everyone,

 

The governmental requirement for the particular country is that the broadcast station keep three months of recordings of *all* non-music programming in case auditing is needed in the future. Rigging up closures in the automation to stop/start the recording each time it goes into or comes out of a music block would probably end up being too complex, so for simplicity this should probably just be a “record everything and automatically break it up by hour/block of hours/day”.

 

Given those realities and the reality of storage space not being unlimited, a solution would need to be able to: 1.) record at a low sampling rate, 2.) autosave on a user-determined periodic basis, and 3.) ideally, auto-purge old files based on an adjustable interval (3 months in this case, but that could change in the future).
