Notice

Please be aware that much of the software linked to or mentioned on this forum is niche and therefore infrequently downloaded. Lots of anti-virus scanners and so-called malware detectors like to flag infrequently downloaded software as bad until it is either downloaded enough times, or its developer actually bothers with getting each individual release allow listed by every single AV vendor. You can do many people a great favor when encountering such a "problem" example by submitting them to your AV vendor for examination. For almost everything on this forum, it is a false positive.

was done mainly to see what libspeex's resampler is like, nothing more.
Requires SSE, though I doubt thats a problem these days....

Hi. I've got some strange clicks on a left chanel after converting this sample to 32-bit float/48 kHz with spxresample (quality 10).

Hmmm, sample's 404ed. Any chance of a link, so I can forward the problem to jmvalin?

Any stereo signal is enough. For example, sweep://10-22000,50 and "Convert mono to stereo" DSP before the resampler.

so I can forward the problem to jmvalin?

I'm not sure that the problem is in speexdsp lib. Several months ago I took SoX resampler plugin and replaces SoX with Speex library, and it works without problems.
