For high quality voice recordings of your Skype conversation, please use the following settings
- Recording Mode: Stereo – 2 channels
- Sampling Rate: 16000 Hz
- Bit Rate: 128 kbps
The first three can be configured from the ‘Recording’ tab of the configuration dialog. The last two are in the ‘Advanced’ Tab.
- First and foremost, use a headset instead of the inbuilt speaker and mic. It helps to keep the background noise to the minimum and reduces the possibility of any echo during the call.
- If you get an echo then drop the call and try again. If possible, record a test call first and play it back to make sure things are fine.
- For SkypeOut and Conference calls, ensure that the call quality is good enough before you start the recording. Make a few test calls before the actual one if possible.
- Close all other applications which might use your internet bandwidth during that period. Usual browsing should not interfere but downloads or uploads (or BitTorrent) severely hampers the call quality.
- If possible, reboot your machine once before you start on the call. It clears up the memory and performs better.
- Finally, keep an eye on the status displayed at the bottom of the Toolbar as well during the call. It should be showing ‘Recording in progress’. If not restart the call and the recording.
Technically speaking, these settings are optimal for our system. The Speech Recognition engine that we use works in the wideband mode (16 kHz) and the 128 kbps bit rate preserves the optimal voice quality in the mp3 files. Encoding in two track mode enables us to split up each of the track separately and process them.
