Cavern QuickEQ troubleshooting

Here are some common solutions to issues related to QuickEQ measurements and imports. If your issue is not on this page, or it wasn't solved perfectly, don't hesitate to contact the developer.

The system sounds exactly the same

Check the common mistakes under an export guide. For example, for Equalizer APO, you should disable ASIO and bitstreaming.

The system sounds worse

There are many things that can disrupt a measurement. Check the following list with solutions to each of these issues:

  • Don't use any other calibrator - Calibrating an already calibrated system will nearly always produce worse sound, you can't stack the results of multiple software or even multiple results of the same software. Disable other automatic calibration software, and remove previous QuickEQ results.
  • Don't use upmixing while measuring - If the measurement signal goes through spatial upmixers, the measurement signal of a single channel will be divided between more channels, and their result will be averaged. When you apply this measurement, the upmixer could move the calibrated sound to another channel, which requires a different EQ. Disable any upmixing solutions for the time of the measurement.
  • Combat noise - Check the impulse responses. If all you see is a large spike for each channel and some falloff after them, your measurement was fine. But if most of the impulse is not nearly a flat line, you should increase the measurement duration or gain to get a better signal to noise ratio.

The system is too quiet after measurement

Cavern was designed for 0 dB headroom. This means the maximum of the EQ will be at the old output level, and everything else is quieter. This has the advantage of never reaching the 0 dB threshold for example in Equalizer APO, where it would cause massively decreased dynamic range for the loudest effects. If you have an option to increase the analog gain (like on a subwoofer), you can correct this to some extent. For example, if all your channels peak 1 dB below your subwoofer, then add 1 dB amplification on your subwoofer's gain control, then you can increase each other channel's gain with 1 dB in Equalizer APO. This will result in exactly the same setting, but with larger peak system volume and depending on your configuration, possibly lower noise. If all your amplifier blocks can be controlled separately, set the gains so that Cavern will set all channels to their highest possible gain. But if all you have available is the digital control, and the desired peak volume of the system is still not enough, you can just add the same gain to each channel, but keep in mind that this can result in dynamic range compression.

Checking the measurement with another software shows different results

Check the following:

  • Use the same smoothing
  • Use the same calibration files, if you can - for example, when using both 90° and 0° files, Cavern creates intermediate calibrations, so the measured result might not look similar to Cavern's measurement
  • Don't double calibrate (like applying your microphone's calibration file for the sound card)
