Playback sound (often after being mixed) that can be sent to one or more outputs, such as speakers, additional processors, or a recording medium; Conversion between different audio file formats, or between different sound quality levels. Typically these tasks can be performed in a manner that is non-linear. Audio editors may process the audio ...
Vinyl records are easily scratched and vinyl readily acquires a static charge, attracting dust that is difficult to remove completely. Dust and scratches cause audio clicks and pops and, in extreme cases, they can cause the needle (stylus) to skip over a series of grooves, or worse yet, cause the needle to skip backwards, creating an unintentional locked groove that repeats the same 1.8 ...
Machines for these formats had their own transports built-in as well, using reel-to-reel tape in either 1/4", 1/2", or 1" widths, with the audio data being recorded to the tape using a multi-track stationary tape head. PCM adaptors allowed for stereo digital audio recording on a conventional NTSC or PAL video tape recorder.

The smallest signal without dithering is 1, so the number of different levels is one less, 2 16 − 1. So for a 16-bit digital system, the Dynamic Range is 20·log(2 16 − 1) ≈ 96 dB. Sample accuracy/synchronisation Not as much a specification as an ability.
The practice of focusing on loudness in audio mastering can be traced back to the introduction of the compact disc, [3] but also existed to some extent when the vinyl phonograph record was the primary released recording medium and when 7-inch singles were played on jukebox machines in clubs and bars.
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.
