This is a digitised version of the 'How Do I Pass the Redacted.ch interview' pdf guide.
Analogue vs digital
Analogue
- Needs to be converted from analogue → digital (eg FLAC, MP3) via converter to a file that the PC can read
- Analogue medium: Stores music in an object being physically altered to produce sound
- Examples
- A tape recorder changes the magnetization of magnetic tape in a cassette tape to record sound. Plugging a tape deck into a recording device makes a digital copy of the analog cassette tape.
- A record cutter carves grooves in a vinyl record to make a physical representation of the sound. Ripping vinyl through a preamp and into a sound card makes a digital copy of the analog vinyl
- Allowed
- Vinyl (always)
- Cassette under strict conditions
Digital
- Already encoded as a PC readable format
- Digital medium: object storing music in digital files (a binary number string)
- Examples
- CDs
- DVDs
- Super Audio CDs (SACD)
- WEB store downloads (iTunes, Amazon, etc.)
- Allowed
- after using spectral analysis to check for lossy transcodes
Why analogue or digital?
- Some people prefer the “feel” of vinyl and think that music on vinyl records sounds “warmer” and “fuller”
- Others think that digital sources provide an unadulterated and pristine listening experience.
Audio format
- a type of computer file that stores music. Music formats are either uncompressed lossless, compressed lossless, or lossy
- Bitrate: number of bits conveyed/transferred within a unit of time. Units = kbps (kilobits per second). eg CBR file has 320kbps
- Transparency: When the audible quality of a lossy file is such that the difference between the lossless and lossy file cannot be a differentiated by a human ear. Usually MP3 192kbps CBR is considered transparent
