A video monitor with built-in speakers or line-out may not delay sound and video paths equally. Some video monitors contain internal user-adjustable audio delays to aid in correction of errors. Some transmission protocols like RTP require an out-of-band method for synchronizing media streams. In some RTP systems, each media stream has its own ...

Before Windows 7, Sound Recorder could save the recorded audio in waveform audio (.wav) container files.Sound Recorder could also open and play existing .wav files. To successfully open compressed .wav files in Sound Recorder, the audio codec used by the file must be installed in the Audio Compression Manager (ACM); Windows installations dating back to at least Windows 95 came with a selection ...

Compact Cassettes may have a response extending up to 15 kHz at full (0 dB) recording level. [17] At lower levels (−10 dB), cassettes are typically limited to 20 kHz due to self-erasure of the tape media. The frequency response for a conventional LP player might be 20 Hz to 20 kHz, ±3 dB.
In January 1971, using NHK's PCM recording system, engineers at Denon recorded the first commercial digital recordings. [ note 1 ] [ 21 ] In 1972, Denon unveiled the first 8-channel digital recorder, the DN-023R, which used a 4-head open reel broadcast video tape recorder to record in 47.25 kHz, 13-bit PCM audio.
Before loudness normalization, one song in a playlist might be quieter than the rest, so the listener would have to turn a volume knob up to adjust the playback volume. [4] Depending on the dynamic range of the content and the target level, loudness normalization can result in peaks that exceed the recording medium's limits, causing clipping.
