FLAC options (request for more)

I'm frequently using BWF (broadcast wav) audio files that contain meta-data (like TimeCode values). FLAC 1.2.1 is capable of including these meta-data in the flac encoding, but Max doesn't seem to offer this functionality. It would be great if Max could allow the user access to more FLAC options. Th...

Re: Request for an ABX and ABC/HR application

Not much more to do until he Stephen, or someone else, start coding. I'm beyond swamped at the moment. I still am interested in writing an ABX application, but I just don't have the time right now. Hopefully in a month or so I might be able to get started. Just a short message to let you know we're...

Re: Request for an ABX and ABC/HR application

It's been a while since the last post. If sbooth is still willing to give it a try, we will have to assemble a list of requirements to get him started. Krmathis, are you still here to help ? I've also asked for help at the chair of the AES Technical Committee on Perception and Subjective Evaluation ...

A few updates: - ff123 (ABCHR for windows author) has offered some help. - schnofler (java ABC/HR author) is also prepared to help out, when needed. He might also be prepared to improve his java application for the Mac platform. How detailed should a list with specifications be? Should the items be ...

Happened again. Stuck at 98% on the 2nd track of another disk. 'Stop' doesn't seem to actually stop ripping until the UI updates again. I've had the same problem. It seems as if stopping the re-reading of the drive is beyond the control of Max. It's possible to quit Max, but that will terminate all...

But it don't make sense to ABX two files with identical sample rate and size. Sure it does ! Examples: - compare different dither versions, all at 16/44.1 - compare different cd-masterings, all at 16/44.1 - compare different AD converters, all at the same rate I've sent an email to ff123 (ABC/HR de...

An ABX application are used to performed blind comparison tests between two audio files. * One file being the lossless source. PCM (WAV or AIFF), Apple Lossless, FLAC, etc. * The other file being compressed by a lossy encoder. MP3, AAC, MusePack, etc. IMO it's not only about testing lossy encoders....

Request for an ABX and ABC/HR application

Double blind listening tests are important to verify if presumed audible differences are really audible (in the current test setup). PC users have several software tools to perform ABX tests ( http://www.pcabx.com/ , http://ff123.net/abchr/abchr.html ). There doesn't seem to be a good ABX tool for t...

Re: audible differences

As stated earlier in the thread, before you do any listening it's essential to verify if the audio data are identical. If the data are different, there is some problem in at least one of the ripping procedures. If different cd's with identical data sound different on your system, the system is broke...
