Transcribe FLAC to SRT subtitles on Mac.

Local file processing, by renaming the file in Finder. No converter window and no upload queue.

Finder rename

report.flacreport.srt

How the rename works

  1. 1

    Start with report.flac

    Put the FLAC file in a folder RenameTo watches, such as Desktop or Downloads.

  2. 2

    Rename it to report.srt

    In Finder, change .flac to .srt, then press Return. The rename is the command.

  3. 3

    Find the SRT beside it

    RenameTo produces the requested output and keeps a restorable backup of the original.

What happens under the hood

Apple Speech recognition processes the FLAC on your Mac and writes the result as SRT. The source file is not uploaded for transcription.

About the formats

FLAC is losslessly compressed audio. SRT is the plain-text subtitle standard.

Questions, answered

Does my file get uploaded anywhere?

No. File processing happens on your Mac. RenameTo does use the network for license validation, trial activation, and update checks, but your source files are not part of those requests.

What happens to the original FLAC file?

RenameTo keeps a backup before processing. Undo restores the original alongside a format-changing output and does not delete that output. If the original name is already occupied, the restored copy gets “(restored)” in its name.

Can I convert a whole folder?

Yes. Rename multiple selected files in Finder and RenameTo queues each supported conversion, with a separate result and backup for every file.

Can I run the same conversion from a script?

Yes. The CLI command is: renameto srt *.flac
