Speed correction that corrects not just wow but random
variations and long-term rises and falls in speed
Speed errors encountered in recordings and upon playback can be caused by
many problems. Examples include 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 the user interactively 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 and available though CEDAR's worldwide
dealer network. |
