Live-rec allows you to continuously record an audio source and make long term storage, usually for legal purposes, sometimes for later retrieval. If you choose right the balance between quality Vs storage, you will be able to have many months of broadcasted backup.

Recorded audio files are only erased when you reach a predefined capacity limit. When you reach the limit, live-rec will erase just the needed files to keep recording until it check again.

Live-rec is a somewhat simple set of scripts made in Bash and Perl, however they are very effective. Live-rec features are:

• Audio source is encoded on the fly to mp3 or ogg, while maintaining low cpu usage;
• Crontab infrastructure is used to schedule the more intrincate recording times you need;
• Enabling the web interface, you can download your recorded files remotely;
• Audio recording quality can be tuned for your convenience, allowing you to balance between quality Vs recording capacity. The lower the quality, the longest time you can record;
• With one 120GB hard disk, you can easily record more than 14 months of broadcasted content;
• Data is stored in a tree of dates for easy indexing, while allowing for a quick filesystem listings;
• You can cleanup old recordings based on used capacity in MBytes or as a percentage of the usage for the partition where the recording lies;
