If you want a , let me know your speakers and room size – I can suggest starting filter values.
Let’s say your speakers are too close to the wall, causing a 12 dB peak at 80 Hz. Here is how to fix it with the HQPlayer equalizer.
| Do | Don’t | |----|-------| | Use (±3 dB max for cuts, +1–2 dB for boosts) | Boost below 40 Hz (wastes headroom, risks clipping) | | Enable auto-attenuation in HQPlayer’s settings to avoid digital clipping | Apply EQ when upsampling to DSD (requires PCM → DSD, degrades DSD purity) | | Check overall level with a true-peak meter after EQ | Use multiple steep cuts – phase distortion accumulates |
参量均衡器允许用户精确控制频率、增益和Q值（带宽），是最灵活且对计算资源最友好的EQ方式。HQPlayer内置的参量均衡器支持两种相位处理模式：线性相位（linear phase） 。 hqplayer equalizer
: Using PEQ text files is often preferred over convolution because the filters are sampling-rate agnostic, meaning you don't need separate filter files for different input rates.
