Can't run ssr-binaural: default_hrirs.wav" has sample rate 44100 instead of 48000!

[Harvie]

I'm running SSR 0.4.2 on archlinux and when i execute ssr-binaural it gives me this error:

terminate called after throwing an instance of 'std::logic_error'
  what():  Error loading HRIR file: apf::load_sndfile(): "/usr/share/ssr/default_hrirs.wav" has sample rate 44100 instead of 48000!
Aborted (core dumped)

Try re-starting your jack server at 44100 Hz.

[Harvie]

Yes, that works. But i want to use SSR with pulseaudio via pulseaudio-jack compatibility layer. And changing pulseaudio sample rate didn't helped.

[mgeier]

If you want (or have) to use 48000 Hz, you can simply re-sample the bundled HRIRs. Or you can choose any other set of HRIRs that's available in the right sampling rate.

The SSR does currently not resample any impulse responses, see also #32 and #16.

[Harvie]

does it really make sense to recalculate HRIRs to higher sample rate? i mean: you will not get higher quality or something... maybe it's ok to only convert sample rate of final rendered wave just before the output to soundcard.

[JensAhrens]

No, you do not get higher quality by upsampling, of course. People suggested upsampling so that you can readily process all your 48-kHz-files in SSR. Resampling the HRIRs is certainly less effort than resampling the output of SSR.

[mgeier]

You most likely all know that already, but just for the record:

The SSR can and will re-sample "normal" audio files that are used as sources in a scene (thanks to Ecasound with libsamplerate support). The limitation is that the HRIRs/BRIRs/WFS pre-filters have to match the JACK sampling rate (or vice versa).

But in any case it shouldn't then just abort with an unhandled exception, should it? Here is what I get when running ssr-binaural on Manjaro with Jack running at 48 KHz:

You are absolutely right @agraef, letting the exception bubble up is very lazy.

The latest master version has some basic exception handling, though:

https://github.com/SoundScapeRenderer/ssr/blob/85dc4d5b6a9a6c5fb3aa0d75d9d818496286c71b/src/ssr_main.h#L56-L60

I've even added signal handling recently: #230

Unfortunately, there hasn't been a new release since ...

[agraef]

@mgeier No worries, it's just something I ran into, and coming here I noticed the existing bug report. I'll try the latest master then. In fact, I'm mostly interested in the Pd externals, and as these aren't included in the Arch package, I'll have to build SSR myself anyway.
