Would you please add one more configuration setting, which do upsample 4x for [0, 48]kHz and 2x for (48, 96]kHz source.

Thanks.


You can do this with SoX_resampler_mod.

Just add 2 resamplers to DSP chain. First makes 4x upsampling and passes 64000,88200,96000 unmodified. Second makes 2x upsampling and passes 128000,176400,192000 unmodified.


Oh, I see. Great tip!

But, could you please provide the binary of modded version of 0.5.4.1+SSE2?

It is possible to do x64 bit version of plugin?

well. request useless. 'll just wait for the mass transition to x64

Try this simple plugin. It adds 2 entries to DSP: "2x upsample w/o lpf" and "2x downsample w/o lpf".


Please consider adding “2x upsample with linear interpolation” to foo_dsp_resamp.

Why do you want it?

I'm confused  Mod allows upsampling only up to 48000. How come you write about 64000,88200,96000, etc?

You can choose target samplerate. Works here flawlessly.

I recently modded my X-fi Prelude with removing 24mhz crystal and connecting an external clock generator with same value due to jitter. After this mod, I managed with failure of playback 44.1k files. Since that I don't know how fix this via another hardware mod, i went to resample during playback all my archive (most 44.1khz flac) to a value which X-Fi chip natively supports it (aka 48/96khz). Then I find Sox resampler here.

I wonder that is there any comparision between X-Fi's native resampler vs. Sox even I know that Sox resampler one of the best out there.

Thanks to lvpcl and Sox team for this great fb2k component anyway..

In the 0.5.4.2, what is the difference between the mod and the mod2 versions?

Re: Resampler plugin

Reply #112 –
mod: It doesn't resample the frequencies that you enter in the text field.

mod2: It resamples only the frequencies that you enter in the field.

Re: Resampler plugin

Thanks for the new version! Please consider releasing processor optimized versions for mod and mod2.

Re: Resampler plugin

That really depends on the resampler library itself. I don't think many compilers will just automatically parallelize/vectorize the entire process and magically make things faster.

I just downloaded the v. 0.5.4.3.

I have a K10 (a Phenom II). Should I use K8 or Dual Core or should I try to run my own tests?

The packaging is now different. The mod package is separate and it does not contain optimized versions. Are the mod versions "MSVS generic" ? The v. 0.5.4.2 included SSE2 mods.

"Core2" is for Intel Core2 Duo/Quad processors. So I suppose that you should use K8.

Anyway, the performance increase is very little (about 10% or even less), that's why

Yes.

Thanks.

I did a quick test. I converted 25 short wav tracks (~350 MB) from 44.1. to 48k. I ran the test set five times in a row with each different compile. The sample rate conversion settings were default. Foobar used all four CPU cores.

Here are the results:

I can't make any conclusions. The results are too varied.

You can use foo_benchmark for tests. Just use 32-bit float WAV file as an input.

For 16-bit input files, foo_hdcd and foo_input_dts.dll will also be called. This will slightly decrease actual speed.

Only for the first 5 seconds or so worth of data, unless there's anything to decode. I suppose this still has a noticeable effect on benchmarks.

wav "decoding" speed w/o foo_hdcd and foo_input_dts:
32-bit: 6000x realtime
16-bit: 10000x realtime

with both foo_hdcd and foo_input_dts:
32-bit: 6000x realtime
16-bit: 2800x realtime


Well, it seems that this difference (10000 vs. 2800) is negligible when resampling speed is only ~90x realtime.

The version 0.5.4.3 was for all types of processor (atom, core2, K8) SSE2 version, so there are also other processor specific optimizations there, right?
Will there also be  procesor specific version with SSE3 instructions enabled? Version 0.5.5, which is SSE3, is common for all procesor types. (but maybe i am completely false). Difference between v. 0.5.4.3 (K8) - definitelly faster as generic - and 0.5.5 is negligible on Athlon 64.
Thanks to lvqcl for further improvements of his component.
