In secure mode this is completely anal about doing multiple reads until it finds consistency.

In the Windows world the most respected ripper is EAC (Exact Audio Copy). File hashing is not reliable as a way of establishing the integrity of different rips, Unfortunately for music rips there tends to be extraneous data like album art and metadata and, in the case of FLAC files, the bit pattern of the audio data will vary according to the compression level used, even though in each case the data expanded from it will be identical. There are many programs which can generate them. When first I read your post, Paul, I thought immediately about the file hashes which are used to verify the integrity of file downloads. Different pressings of the same CD can have subtly different offsets (not important for audio listening, but significant for data verification) and CD drives have different capabilities for reliable extraction (from memory the Plextor 230A is the best).

The ripping software is a later stage in the extraction process. Those that prefer high definition all seem to call it more “musical”, which I take to mean subjectively they want it to sound better but can’t explain what difference they think they can hear.

More worryingly, those that can tend to prefer 16 bit because it sounds less clinical. Most of the audio community are still stuck as to whether double-blind you can reliably tell the difference between 16 bit and 24 bit. I was surfing in the bath, googled “CD v WAV”, realised this thread is about whether two 16/44 formats sound different. It struck me as the first time I remember actually hearing error coming through in the digital signal and wondered how often, if at all, anyone actually hear data errors. I switched to a non-reclocking streamer and the problem disappeared. It was apparently due to the sending steamer’s reclocking having some incompatibility with the receiving device’s digital card, that also does reclocking. Pops and clicks like vinyl, every 10 to 20 seconds so. I had digital noise form my system recently. The other one I was reading about is ethernet signal packeting that has error correction so it can never be wrong, hence any ethernet cable will do. On the occasion I’ve used dbpoweramp it had error correction checks. I assumed all CD rips have error correction. High res streams are always fixed bit rates, 24/192 is about 5600kbs, which I always think is a vast amount of data for negligible or inaudible difference in sound quality.Ĭhris, you make a good point about error correction and when it is present. It is curious watching the Qobuz player, which streams 16/44 as FLAC, the data normally ranges from around 350kbs to 1000kbs, it never gets very close to 1441kbs.

I therefore have no problem with the idea of compressing redundancy in WAV files to save disk space or streaming bandwidth. Lives would have been lost otherwise, given the nature of the programs.

Moreover, when computer chips were expensive we used to thin down Fortran code to take out redundancy. Don’t tell me audio data is any different from software data or any other digital data. I therefore assume that to suggest otherwise for audio data is being paranoid. Logic tells me that computer companies used to supply software alternatively on CD and download, and they are identical. The WAV was a direct copy and FLAC was lossless compressed. I can’t say I could ever hear any difference between CD, WAV or FLAC and I was assured there should be none.

The WAV was checked to the AMG Pro database. The ripper server could play the CD, rip it to WAV, convert to FLAC and also did an MP3 version at the same time. It was a bit perfect rip using software licensed to several companies including Naim. I ripped my entire CD collection about 6 years ago.
