Speed
The pitch moves with the rate.
From 0.25× to 2.00× the note does not stay flat. Faster playback lifts the pitch. Slower playback drops it. Each site keeps the speed you set.

NEXA Equalizer
Reverb, 5-band EQ, and speed with pitch change for tab audio.
On applies reverb, EQ, gain, and stereo on every tab. Speed stays on the page and pauses while Off.
Reverb
The hit lands. The tail stays.
Reverb keeps a piece of the sound after the source stops. More mix, longer answer, still inside the tab.
Room
The space between the speakers.
Room decides how wide that tail is. Turn it up and the sound fills the gap. Turn it down and it stays close to the speaker.
EQ
Five bands. Each one moves alone.
From −12 to +6 dB. Low moves everything under it. High moves everything over it. The three between them stay on their own frequency.
Gain
A quiet tab, brought forward.
Gain runs from 0 to 4 dB. The same voice gets stronger. Nothing is uploaded to do it.
Stereo
Narrow the sound. Leave the room wide.
Move the stereo slider and the audio pulls toward the center, down to mono. The reverb stays wide around it.
