Should you convert RM to FLAC?

Yes, when you only need the sound: a song from a music video, the audio of a lecture, or a voice recording to transcribe. The picture is left out and the soundtrack is saved as FLAC.

RM is RealNetworks’ streaming video format from the dial-up era; FLAC is lossless audio at roughly half the size of WAV. Use FLAC to archive music and recordings you may want to convert again later.

How to convert RM to FLAC

  1. 01

    Add your RM

    Drop your RM video onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to FLAC. Change the bitrate if you want to; the defaults suit most files.

  3. 03

    Save the FLAC

    Press convert and save the FLAC. Several files come back together as a ZIP.

What changes when RM becomes FLAC

FLAC is lossless, the soundtrack usually isn’t

The audio inside an RM is almost always compressed already, usually as RealAudio (Cook). FLAC preserves it exactly but makes a much larger file without sounding better. Choose it for editing software; choose MP3 or M4A for listening.

Video files without sound

Screen recordings and some exported clips have no audio track at all. The file is checked as soon as you add it, and you’ll be told before converting if there’s nothing to extract.

This page is put together from our notes on each format, choosing only what is true of RM and FLAC, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Uploading a whole video to keep only its sound wastes time and data, and hands over the footage too. The audio track is read and saved right here, and the file never leaves your device.

How to check for yourself

Worth knowing

  • About the RM. RMVB files use variable bitrate and play at the wrong speed in some tools; converting gives a normal, steady MP4.
  • About the FLAC. FLAC made from an MP3 is lossless only in name: it perfectly preserves an already lossy recording, at five times the size.
  • AVI, WMV, FLV and other older formats use the FFmpeg engine, a one-time 31 MB download.

Questions

Does extracting FLAC from an RM lose quality?

No. FLAC stores the soundtrack exactly as decoded, although it can’t improve on the compression already in the video.

Can I get the audio from only part of the video?

Yes. Set a start and end time before converting, and only that section is saved as FLAC.
