'Create audio clip files for use with I²S Speakers' is wrong

On the web-page https://esphome.io/guides/audio_clips_for_i2s it is specified:

  • Using Audacity, convert audio to WAV, mono, 16kHz, Unsigned 8bit PCM

This is wrong. It should be: Signed 8bit PCM.

Side note: Audacity can export RAW as well.

Then hit the link at the bottom of the page that says “edit this page on GitHub”

Have you successfully created raw data that is played at the correct speed for the entire duration?

Audacity (Windows) doesn’t seem to offer Signed 8bit. Only unsigned 8bit.

Can you please share your entire process?
