MSSRecorder is an ActiveX control for sound recording and playback. Recording and playback is to and from disk files, so recording is limited only by the amount of available disk space. Features of the control include: a configurable peak level meter display\; support for recording and playback of PCM WAV files, mono or stereo, with sampling rates from 192000 down to 6000 samples per second\; the ability to insert tone markers each time recording is started and or finished\; the ability to set a maximum recording duration\; the ability to start recording or playback at any point within the current file\; support for recording to temporary files that are deleted when closed, or working with new or existing permanent WAV files\; and the ability to pause recording or playback at any time. Event callbacks and state monitoring properties allow recording or playback progress to be monitored. MSSRecorder is packaged with QuickRecord, a sample application demonstrating its capabilities.
