Cedar Audio has claimed another ‘world first’ with its Respeed speed correction process, addressing wow and random variations, as well as long-term rises and falls in speed.

Cedar Audio RespeedSpeed errors encountered in recordings and upon playback have a variety causes – faulty tape recorder transports, sticky tapes, electrical problems in analogue recording devices and off-centre holes in disks that lead to wow. In each case, the recording or the replayed audio exhibits speed changes with respect to what would have been recorded or replayed had the fault not existed.

Respeed automatically identifies – or allows users to identify – unwanted speed changes contained within the presented audio. Once these have been determined, the track may be processed many times faster than real-time. The result is greater pitch stability and, when used on speech signals, improved intelligibility. However, musical pitch variations such as vibrato and glissandos are left unaffected.

Respeed incorporates three modes of processing, including an Advanced mode that handles many tracks without user intervention. However, a powerful range of tools are also provided, and these allow the user to adapt the process for almost any track that contains speed errors.

Correction is not limited to wow. Respeed will address random speed fluctuations and even continuous rises or falls in speed caused by problems such as failing batteries in analogue recorders.

Respeed will be available in Q2, 2011 though its worldwide dealer network.
