Wavelet

A quick rundown on each feature and its settings

Wavelet

Legacy mode

Legacy mode is turned off by default, because features will become available whenever a compatible music application starts an audio session while Wavelet is running. If no features show up while you’re playing music, you can try enabling legacy mode and see if Wavelet will process your music in this mode.
Spotify, YT music, Shuttle, Phonograph and Google Play Music open audio sessions, thus features in Wavelet will show up. Poweramp will work in default mode too if you enable musicFX in Audio engine - Advanced Tweaks and then enable MusicFX on the middle page in the equalization settings. Tidal, YouTube, Soundcloud, Qobuz, Neutron, VLC, foobar2000 and most music apps that came preinstalled on your phone might work in legacy mode, depending on your device manufacturer’s audio framework implementation.
You will have to experiment with legacy mode and see what works best.

Reduce clipping

By enabling clipping reduction, you allow Wavelet to process audio in a bigger time frame (150 vs 22ms) This reduces clipping at cost of increased latency. Recommended when listening to music but not when watching videos.

AutoEq

The AutoEq feature contains precalculated results from jaakkopasanen’s great work. Over 2300 entries are shipped with Wavelet and contain the optimal frequency response compensation for those specific headphone models.

Graphic equalizer

The graphic equalizer consists of 9 bands. You can set each slider independently to change the balance in frequency response or to remove obvious imbalance issues. You can also use this feature to compensate the frequency response of your speakers or your headphones if they’re are not listed in the AutoEq section, or if you would like to add some coloration to your audio stream.

Bass boost

Bass boost amplifies the lower frequencies.

Reverberation

Reverberation adds the effect of a sound bouncing of the wall from a room you would be listening in.

Virtualizer

Virtualization is the effect of spatializing audio channels. This effect will widen the stereo image (when listening in stereo).

Bass tuner

Bass tuner allows you to set a very precise bass boost or reduction. This can be useful if your speaker system has a resonant peak in the lower frequencies or a point where long soundwaves cancel each other out.

Limiter

The limiter removes volume spikes from your audio streams. Sometimes this is desired in noisy environments where you need to turn up the volume in quiet parts of the music and later turn it down when the music becomes louder.

Channel balance

Channel balance allows you to control the left and right channel output volumes separately. This can come in handy when you can’t sit in center of your speaker setup or when your headphones have a difference in impedance between their left and right channels. Some phones have a limiter built in that causes volume ducking when you boost above a certain amount of dB. You can also use this feature to control the overall volume output and to prevent this ducking from happening.
