Frequently Asked Qestions

When DSD64 to DSD256 is converted, output level is -12dB?

As rule, DSD output is set -6 dB for 0 dB PCM input. It's headroom to protect against broken stability of DSD modulator due to overload. Read more...
AuI ConverteR's DSD output allows -0.4 dB for 0 dB PCM input, as default. The software has own original protection method. It doesn't fully solve the stability issue, but add overload tolerance for AuI's modulator.
If an input signal has very significant spectrum energy and AuI's modulator stability is broken (noise, silence, tone at output), it's need to attenuate output signal manually or set auto normalizing target level lesser up to several dB.
