Greetings.
My "multimedia machine" (MM) is now my PII 233mHz 160mb RAM laptop from 1998 (now with XPP and a 250gb HDD). I have been working for the last few years to squeeze every bit of functionality out of it - and can't believe how much progress I have made! I play MM files on it while I work on my more modern/powerful XP laptops.
I use SpectrumLab
http://www.qsl.net/dl4yhf/spectra1.htmlas my spectrum analyzer - now with Trout as my mp3 player.
Trout's features with low CPU usage are great; however, I only use Trout on my PII because the PII's CPU usage limits require low CPU usage software.
I played the mp3 sample on my P4 1.8gHz 1gb RAM laptop with XPP (and two internal HDDs ...). When I played the mp3 in Trout with bass.dll 2.4.6.0, I heard the "skip" at 1:40 & 1:55 & 2:10 & 2:28; HOWEVER, when I played the mp3 in Trout with bass.dll 2.4.7.1, I did NOT hear the "skip"! so ... that seems to be GOOD NEWS. I played the mp3 again in Trout with bass.dll 2.4.6.0 and heard the "skip" again at the same times ... in case you are curious to try that ...
I have another question here»
http://www.hydrogena...wtopic=83558&hl=One of the MM players I use is JetAudio.
I really like the (OLD) 122C custom GUI/skin someone made.
It has a nice spectrum analyzer. (I have always had to have spectrum analyzers when I play audio - in my old HiFi, in my cars & now on my PCs...). Anyway, every mp3 player (except JA) has less CPU usage with mp3 at lower bitrates. (That is not, however, why I made - years ago - many mp3s at lower bitrates. I have found that keeping the sample rate at a minimum of 24khz is important. 22050 is noticeably worse than 24kHz ... Lower bitrate mp3s at 24kHz ofter require low-pass filtering when encoding. I use Lame Front-End

Anyway, on my PII JA plays 128/44.1 mp3s at about 50% CPU usage but plays 96/32 or 48/24 or 32/24 mp3s at 100% CPU usage - which causes playback lockup.
I'm not sure why JA does that? I can only guess that JA resamples the 32/24 kHz mp3s to 44.1 which causes the much higher CPU usage? I would like to "solve" this problem somehow/sometime ...
Any ideas?
Many thanks & kudos in any case ...
