Speed and pitch, separately
Changing playback speed normally changes pitch too — faster sounds higher, slower sounds deeper, like a record player. That’s the “nightcore” and “slowed” effect, and it’s produced instantly here as a WAV file. When you keep the original pitch, your browser time-stretches the audio as it plays, which is ideal for lectures, podcasts, audiobooks or practicing a song at a slower tempo; the tool records that playback, so saving takes as long as the new length of the track.
Cut the part you need first with the Audio Trimmer, or play it backwards with Reverse Audio.
