StreamPix 4/ Bwave Audio Recording Module
The Bwave Audio Recording Module allows users to record audio sources to a separate wav / bwav compatible file, while the video is recorded to a StreamPix sequence file. Furthermore, great care has been taken so that the module maintains audio signal in source with video, provided there is sufficient disk bandwidth available for recording both media.
The module generates 3 possible audio file formats:
- Standard wave file;
- Single bwave file: The whole audio stream is recorded into a single continuous bwav compatible file format (default);
- Multiple bwave: Allows the recording to be paused. Upon resume, a new bwav file is added and linked to the previous file.
Features:
- The module is optionally loaded within a workspace. Hence, it is possible to use multiple modules to allow recording from multiple audio sources (one module per workspace though).
- A wav file is created with the same name as the sequence file created for video recording, with the .wav extension, into the same folder as the video seq file. The audio stream file name extension is always .wav, even if the bwav mode is enabled.
- Upon start recording, video is recorded to seq, while audio is pushed to the wav.
- Audio is recorded uncompressed, the audio stream is picked from any windows compatible audio source. If the audio source includes high quality digitizing options, the module can take advantage of those options.
- Upon stop recording, audio rec is also stopped.
- File | Sequence Close will close both video and audio files.
- File | Sequence Open will open the sequence file and the wav file if it exists (provided the module is loaded into the workspace).
- Playback will launch video playback at recording speed and audio playback.
- Pause / Stop during playback should stay in sync within 50 ms.
- Continuous playback, with loop at the end of the video back to the first frame, will also loop audio.
- All parameters must be adjusted before the sequence and the audio wav file are open. Once the files are open and ready to receive a sample, parameters cannot be changed. When the sequence file is closed, you can access the audio recording parameters again.
- Bwave file format is only supported by QuickTime Player. It is not supported by Windows Media Player. Bwave format is based on wav audio format, but includes extra metadata like time stamp, link to other related bwav files (typical upon non linear editing).
