Description
- Sample rate converter up to 192000Hz.

SSRC Alternatives
SSRC has also been adapted with the plugins below:
Resampler-V - Complete with adjustable phase response, pass/stop band, filter rejection and real-time frequency/time domain graphs.
Available on https://sourceforge.net/projects/resamplerv/
SSRC X - Linear phase is the default phase response.

Because the settings are very unclear in SSRC X, the file contains a read me. However that is encoded in non standard Standard-Japanese for MAC unicode. For convenience this has been converted and translated below;
Foo_dsp_ssrcX - 0.57
This is a modified version of foo_dsp_ssrc that Otchan was created.
SSRC parameters can be set finely. Of course, presets can also be used, in where Default is good enough for most purposes.
The conversion destination sample rate can be specified on the left. More than one can be specified, any of which is automatically selected according to the conversion source sample rate and the formats the output device supports. If conversion is not necessary, conversion is not performed.
Some elements of the original SSRC up sampling are altered. Namely the cutoff frequency of the low pass filter which affects Aliasing in high range to improve rejection.
This plugin was created with the intention of using with XP/Vista KS output / Vista WASAPI / ASIO.
This plug-in performs sample rate conversion using the original SSRC when necessary. SSRC was created by Mr. Shibata, and it is compatible with high level conversion quality, with low load on CPU. This is new a feature.
It is also useful for sample rate conversion of WAV files.
Configuration
Display information on console - enables Conversion status can be shown via the console accessible via "View" "Console" in foobar2000.
Sample rates (Hz) - Check all the sample rate that the hardware can handle.
AA [dB] - Anti-aliasing Rejection (applies to down sampling only). Typical settings:
16 bit sound card 103 dB
24-bit sound card 127 dB
DF [Hz] - Always enabled depending on input/output combo - Its a High Pass Filter.
1M fs - Default SSRC algorithm filter is always enabled for down sampling. Otherwise a custom cutoff can be specified within the range specified below:
50 22.0 kHz (-3 dB) Maximum
500 21.7 kHz (-3 dB)
2000 20.5 kHz (-3 dB)
4000 19.0 kHz (-3 dB)
8000 15.9 kHz (-3 dB)
16000 9.5 kHz (-3 dB) Minimum
When Up sampling this has little if any effect.
The DF differs from the original SSRC algorithm. The DF (Hz) in SSRCX is half that of the original plug-in. For example, DF (Hz) = 50 for this plug-in is equivalent to DF = 100 for SSRC.
FFTFIRLIN - Leave at 1 unless otherwise required Its automatic and reflects AA and DF settings.
