Trout 1.05x playback now "skips" often; 1.0.4.9 never did/does ...

I listened to the whole track but didn't hear anything out of the ordinary.  However, try the latest build (1.0.5.36) and see if that fixes anything.  If you'd like, feel free to contact me via instant messenger since it might be easier to troubleshoot this in realtime.

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.html
as 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.hydrogenaudio.org/forums/index.php?showtopic=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 http://www.pazera-software.com/products/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 ...
Regards,

Confirmed.  I can hear the skip in BASS 2.4.6.0 and not with BASS 2.4.7.1.  So, issue solved?

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 really have no idea, sorry.  I'm far from being some super audio expert or some super professional programmer.  The fact that Trout has such low CPU usage is more a testament to Chris Mallett and Ian Luck than my programming skills.  They're the authors of AutoHotkey and the BASS library, respectively.  I'm glad Trout has found a niche role on your older laptop; I've had several reports from users that they're able to use Trout in that way as well as on machines running Windows 95 and 98.

Thanks for your testing, feedback and patience.

It seems to be solved ... for now anyway.
Does anyone know what the problem/fix was?
I hope this problem doesn't resurface later!

The new BASS DLL fixed the issue.
