I dont agree with the DSP part, u can use this DSP called SRC Resampler. (It is the best resampler for foobar and the best so far i have known for computers)

The usage for this DSP is quite simple, it is used for sound card that do HARDWARE RESAMPLING. For example, Creative Audigy (1) Platinum, sound blaster series and Audigy 2 if i have not mistaken.

Why must the soundcard do resampling? because the sound processor only support processing at 48000hz for those few cards, dont ask me why, ask the company that made it.

The problem with Hardware Resample is that, the quality of the resampling on those cards are done by a low quality processor chip on the soundcard, it will cause distortion on the bass, poor vocal clarity/real-ness and "harsh" treble.

Audio from computer (44100Hz) >>> Hardware Resampler to 48000Hz >>> Sound Processor >>> output

IF u use SRC Resampler, it will bypass the low quality hardware resampler, so...

Audio from computer with SRC enabled (48000Hz) >>> Sound Processor >>> output

see? no nid for the hardware resampling to 48000, as it is already converter on your computer and the sound processor can processor it directly as it already is 48000hz.

*different cards have different resamplers, for example, X-FI's drivers are streamlined and there is no need for resampling because the quality of resampling on the card is TIP TOP. so when u activate SRC on those cards, it wont show any different, as creative has fixed the issue of poor harware resampling. Other sound card brands i dont know, experiment to find out loh ; ) but i'm sure this will work for C-media sound cards, Creative Sound Blaster, Audigy 1,2,4. which have a stupid low quality resample chip ==

Does Replay Gain apply gain in waveform(audio frequency signal) or is it like controling the program's master volume.

Also what is Dither for?

Added on June 28, 2009, 12:19 amIf u're not recording, higher latency better. It does not use up alot of CPU when u set the latency higher. Try setting lowest latency on your sistem, see if it lags or not, on my pentium 4 2.4Ghz it eats up my CPU time like crazy...even opening webpage will lag. There is also no difrerent in sound when higher latency...

If u want me to be more techincal, lower latency will use up more CPU which will jam up the system bus etc and cause the board to produce more EMI interference in the PC, which might affect sound, but heh, i think only dolphines can hear the difference....

If TOO MUCH buffer yes, it will cause lagginess.

If TOO little also it will cause lagginess, because the program is struggling to keep up with such little buffer length by increasing program priority so that the music doesnt lag or stop and continue when u multitask with processer and RAM heavy software (eg. photoshop) So like when you photoshop, the music is still smooth with small buffer, but your photoshop program will suffer.

basically if u use a new generation processor like core2duo, duo core etc...u dont need to worry so much about this. those using pentium 3, celerons or early pentium 4...those without HT will feel the performance drop.

But foobar's SSRC resampler causes average +1dB in the signal when resampling, which is distortion...u can see the in the visualisation "Peak Meter", when the meter crosses over the max (0 dB) to become +X dB.... TTPlayer's resampler does not...

I need the resampler because my Audigy 1 soundcard have to up-sample to 48khz for the DSP to process, and the resample algorithm/chip on that card does it badly...bass becomes soft...weak vocal...harsh and dead trable

If SSRC resample for me to 48khz, the Audigy doesnt need to do that lousy resampling anymore...it just bypasses that lousy on-card resampler...

Last time i use foobar to resample, but got distortion, so now using TTplayer...sound much smoother

And yeap, only audigy and sound blaster live based cards needs to SOFWARE resample due to the lousy on-card resampler... others like X-fi already fix that issue...

PPHS Ultra Mode uses too much CPU on my setup... =\

SoX default config sounds good here...much smoother than SRC SSRC PPHS and TTPlayer... but there is quite an amount of settings to set >< i still dont quite understand the help files also...

Thx for the recommendations

Does ASIO resample to 48000khz? As far as i remember lah, it doesnt so its not good for my soundcard... my sc do very bad job in resampling
