The recording of electrical signals by means of changes in. FM recorders, although not quite as accurate, provide a satisfactory alternative to those methods. An electronic device for recording and playing back video images and sound on a videocassette.
TAPE RECORDER CODE
For jitter and shimmer estimation, direct sampling or the use of a video cassette recorder with pulse code modulation are clearly superior. Put away your high tech gauges, and take a trip down the memory lane with Tape Recorder. virtually obsolete these days, a tape recorder is a self-contained unit that records, plays back, and has a built-in amplifier and loudspeakers.
The recording head of the tape deck consists of a tiny C-shaped magnet with its gap adjacent to the moving tape. The tape consists of a plastic backing coated with a thin layer of tiny particles of magnetic powder. Distortion introduced by any of the data acquisition systems is negligible when extracting average fundamental frequency or average amplitude. tape recorder, recording system that makes use of electromagnetic phenomena to record and reproduce sound waves. Recordings were digitized on playback and with the direct samples analyzed for fundamental frequency, amplitude, jitter, and shimmer using a zero crossing interpolation scheme. To test for possible contamination of acoustic analyses by record/reproduce systems, five sine waves of fixed frequency and amplitude were sampled directly by a computer and recorded simultaneously on four different tape formats (audio and FM reel-to-reel, audio cassette, and video cassette using pulse code modulation).
