Bug Report: Voices tracks' waveforms sometimes display incorrectly

Operating System

• Windows
• Mac
• Linux

What version of the game are you using?

0.3.3 (still present in 0.4.0 - itch.io Version 14)

Have you identified any steps to reproduce the bug? If so, please describe them below in as much detail as possible. Use images if possible.

1. Start any song through the Freeplay menu
2. Open the chart editor
3. If waveforms correctly display and are aligned with voices, either repeat Steps 1 and 2 or switch between Default and Erect variations a few times
4. The waveforms may eventually display incorrectly

Please describe your issue. Provide extensive detail and images if possible.

Occasionally, the waveforms for each side's Voices tracks are highly offset from the song, display the instrumental's waveform instead, or display a completely different song's waveforms. This issue seems to persist for all songs until the game is restarted.

Actual audio and gameplay is unaffected.

Here are some examples:

Spookeez: Boyfriend's waveform displays the instrumental's audio

Blammed Nightmare: Boyfriend's waveform displays the instrumental's audio

Fresh: Boyfriend's waveform is offset

Blammed: Pico's and Boyfriend's waveforms are either offset or from a completely different song

Stress: Tankman's and Boyfriend's waveforms are offset

Tutorial: I've identified these as the waveforms from M.I.L.F.

This is kinda like #2622, but explains more issues with the waveform.
I've seen they're only managed by an array so they might not updated, restretch, or even display the correct audio track

This issue is still present in 0.4.0 (itch.io Version 14)
