How the FLAC do I tell MP3s from lossless audio?

>Had memory been cheaper when the CD was invented, it might have been that reclocking the data - through a first in-first out memory buffer - would have been used; it would have made a noticeable difference to the audio output.

It was featured on Sony 'Discman' portable CD players as 'ESP' - electronic shock protection. It was featured on all MD players because, like a computer HDD, the data was always stored sequentially (you could delete or rearrange tracks on a MD). The amount of buffer varied depending upon the model of Discman / MD player you had - the pricier models tended to have more solid-state memory, expressed in 'seconds' of anti-shock protection.

The Sharp 722 MD player (which has a scroll wheel in 1998) would play reliably in a pocket whilst walking - the cheaper 702 player would occaisionally have to catch up on itself.

This was a year or so before the £600 5GB iPod, and before 32MB (yes, MB) MP3 players were seen in Currys.

[Side note: If Sony hadn't been so awkward about copy protection and propriety formats, a proper High Density Data Minidisc (later versions could do around a GB, normal MDs were about 100 MB) could have pre-empted the iPod's impact on the market. Instead, we had SonicStage software and beautifully designed 20GB Sony HDD players that could only play ATRAC - not even MP3! - years after the iPod. Silly Sony.]
