keeping audio clear together

Grant equipment

As SoundExpert is non-commercial independent research project it can´t afford buying expensive laboratory equipment. At the moment we need high-precision D/A and A/D converters which will allow us to start listening tests of analogue audio equipment and analogue circuits of digital audio equipment. We plan to begin with digital audio players. SoundExpert testing engine is well prepared for such kind of testing already.

Basic features and specifications required:

  • Simultaneous input and output conversions with synchronized clock
  • Standard balanced and unbalanced analogue inputs/outputs
  • USB or FireWire digital input/output
  • Sampling frequency (fs) up to 96 kHz
  • Total (D+A) accuracy of both conversions:
    • THD+Noise: < -100 dB
    • Frequency response: ± 0.1 db within 0….1/2fs
    • Amplitude accuracy: ± 1% within 0….1/2fs
    • Phase accuracy: ± 1.0 degree within 0….1/2fs

We will receive such laboratory instrument with gratitude and this fact will be mentioned on SoundExpert site specially.
