Maximum Paula sample rate in PAL mode?
« on: October 08, 2012, 11:08:30 PM »
I'm going to downsample some of my audio cd's so that I can play them in 14-bit on my Amiga's through Paula in PAL mode (approx 28.8KHz).
I've read conflicting reports scattered throughout the web as to the precise maximum sample rate that is supported under PAL. Some say the limit is 28837 for PAL, with the 28867 limit being for NTSC. Others say that the limit is 28867Hz for PAL and NTSC. Personally, the former seems to make more sense to me. It's only 30Hz difference I know, but I'd like to know the correct answer anyway!

Question number 2: Should the answer be, for instance, 28837, will the playback program (such as HippoPlayer/EaglePlayer/Songplayer/AHI) use that absolute precise playback rate?

Thanks...

Thanks for replies. Still no absolute definitive answer, but I'll go with my instinct with 28837 Hz.
I've played many samples over the years as well, and the only time I had unreliable sample playback was when using AMOS. For whatever reason, AMOS sucks at playing samples, and an intermittent tone change can become apparent (more noticable with higher sample rates). Other than AMOS, I'll say I've had good results with higher rates. The maximum rate that AMOS permits is 28149. And up until now I have always used 28149 as a maximum (outside of AMOS) for all my song rips etc.
I'm not impressed with MP3's at all, so I stay away from them as much as I can. 320KBPS ones are acceptable to me though. They're such a strain on the old 68K processor, so 16bit wav's or aiff's are what I use. With hard drive storage so plentiful these days, I just don't see the point in lossy audio compression.
