How do I compare different versions of an AI-generated song?

Decide what you are listening for

A new generation may have a better vocal but a weaker transition. Comparing whole songs makes it easy to lose the detail that prompted the test. Pick a specific question: which chorus feels clearer, which intro starts faster, or which ending fits your project?

Use an original export from your music tool when it is available and appropriate. Tabtone is useful for a quick listening set made from your own permitted browser playback. It does not normalize volume, align versions automatically or provide an A/B switching interface.

Build a small comparison set

1. Choose a passage of similar length in each version. Note its position in the source player so you can return to it.
2. Open version A in Chrome, pause just before the passage and open Tabtone on that source tab. Select a recording length that covers the clip. The free limit is three minutes per take.
3. Click Record this tab, play the passage and choose Stop & save after it ends. Rename the stopped recording by clicking its large title, for example “Paper lantern — chorus A”.
4. Repeat for version B. If both versions can play from one source tab, you can instead capture them in a single short take with a quiet gap between playbacks.
5. Use Preview to check the proposed clips. For a combined take, adjust Split when silence lasts or remove an unwanted boundary with Merge at.
6. Name the tracks with the version and passage, choose the same export format and MP3 bitrate for each comparison, and export the tracks individually.

Make the comparison fair

Keep the playback settings consistent between takes. If one version is noticeably louder, do not assume the louder recording is the better arrangement. Tabtone has no loudness matching control; use your listening player or an audio editor if that adjustment matters to your decision.

Turn off Trim silence at the start & end when the length of an intro pause is itself part of the test. Otherwise, preview the trimmed starts so one version has not lost context that the other retains. There is no manual draggable range editor, so an exact cut may require a separate editor.

Keep your notes next to the files: “A: clearer vocal; B: stronger final chord.” The names help you connect each decision to the right take later. See how recording and track names work, or use the song capture walkthrough when you are ready to save a longer listening copy.
