How to use this workflow

  1. Establish the reference

    Keep an unchanged source and identify the passage or signal relationship described below.

  2. Share the recipe with the recording

    Add the date, tool name, output filename and one listening landmark. If the learner uses a different source edition, identify the opening event as well as its timestamp. Ask them to report the difficult transition and selected settings rather than only saying the file is too fast. Keep student names and private lesson recordings out of public links.

  3. Verify the saved result

    Reopen the downloaded file and compare the relevant event with the source. Keep the source and the settings note for a later revision.

Fill in a practice recipe from one unchanged source

This invented worksheet uses a 40-second excerpt starting at 70 seconds in an original recording. Independent Speed at 80% predicts a 50-second result while Pitch stays at 0 semitones. It is a planning calculation, not an exported or teacher-tested result. A student should reopen the unchanged source for each version.

Swipe or scroll sideways to read all columns.

Apply the result within the tool’s limits

PitchChanger does not grade student accuracy or automatically progress a practice ladder. Independent Speed differs from Slowed + Reverb, whose playback rate changes pitch too. Write the tool and control names explicitly so the same percentage does not describe two different treatments.

Common questions

Are the example numbers device test results?

No. Numerical examples and worksheets on this page are authored explanations. They do not measure your recording, browser latency or listening accuracy.
