foobar2000 WASAPI output RMAA test report

This is a comparison test between WASAPI and standard playback output of the foobar2000 audio player.

Test conditions:

• Windows 7 Pro SP1 x64.
• RightMark Audio Analyzer 6.3.0 (RMAA).
• foobar2000 v1.2.9 (fb2k) with resampling to 96kHz by PPHS plug-in.
• 16bit/44100Hz audio PCM file.
• WASAPI output with 24bit setting of fb2k component.
• MME API output with 100% of volume level and with 24bit/96kHz settings of Windows mixer.
• Input loop of "What U Hear" (WUH) driver of the Creative Sound Blaster X-Fi HD (Digital Music Premium HD) USB sound card with 24bit/96kHz settings.

As you can see the results below, there is no differences. I'm sure that is because of absence of the resampling process by OS due to using of PPHS in according with Windows playback settings. Maybe it would make sense to use an WASAPI component for the fb2k without PPHS plug-in, to bypass a bad- quality resampling of the operating system, if a sound card supports a different sampling frequencies at hardware level (not a X-Fi HD case).

Testing chain: fb2k MME output -> WUH input:

1. Frequency response (from 40 Hz to 15 kHz), dB : +0.00, -0.00
2. Noise level, dB (A) : -100.5
3. Dynamic range, dB (A) : 98.8
4. THD, % : 0.0004
5. THD + Noise, dB (A) : -92.9
6. IMD + Noise, % : 0.0031
7. Stereo crosstalk, dB : -99.2
8. IMD at 10 kHz, % : 0.0033

Creative Sound Blaster X-Fi HD Sound Card - RMAA test report @24bit/96kHz

This is a line output to line input wire loop RMAA test of Creative Sound Blaster X-Fi HD (Digital Music Premium HD) at 24bit/96kHz. Tests have made without resampling by Windows 7 (x64) drivers by setting it to 24bit/96kHz.

Testing chain: line output (24bit/96kHz.) -> line input (24bit/96kHz.):

1. Frequency response (from 40 Hz to 15 kHz), dB : +0.01, -0.07
2. Noise level, dB (A) : -101.8
3. Dynamic range, dB (A) : 101.8
4. THD, % : 0.0030
5. THD + Noise, dB (A) : -87.1
6. IMD + Noise, % : 0.0042
7. Stereo crosstalk, dB : -96.2
8. IMD at 10 kHz, % : 0.0064
