Oreka GPL 
Open Source Audio Recorder

OrecX Basic GPL free voice recorder is VoIP ready and can capture and retrieve calls via a browser-based interface. Downloaded for free, the Oreka GPL basic solution is the only free voice recording software on the planet that can be downloaded in just 30 minutes and requires no maintenance.

Oreka is a modular and cross-platform system for recording and retrieval of audio streams. The project currently supports VoIP and sound device based capture. Recordings metadata can be stored in any mainstream database. Retrieval of captured sessions is web based.

Recording and storage features:

  • Record VoIP RTP sessions by passively listening to network packets. Both sides of a conversation are mixed together and each call is logged as a separate audio file. When SIP or Cisco Skinny (SCCP) signaling is detected, the associated metadata is also extracted
  • Record from a standard sound device (e.g. microphone or line input). Can record multiple channels at the same time. Each recording goes to separate audio files
  • Open plugin architecture for audio capture means that the system is potentially capable of recording from any audio source
  • Plugin architecture for codecs or any other signal processing filter
  • Automatic audio segmentation so that continuous audio sources can be split in separate audio files and easily retrieved later
  • Capture from multiple Network devices in parallel
  • Capture from pcap trace files
  • Voice activity detection
  • G.711 (A-Law, U-Law), G.722, GSM6.10 and iLBC RTP encodings supported
  • G.711 (A-Law, U-Law) and GSM6.1 encoded wav files supported as storage formats
  • Automatic transcoding from wire format to storage format
  • Recording metadata logged to file and/or any mainstream database system
