Music distributed with Record Union needs to be uploaded in WAV or FLAC format.
WAV and FLAC are high quality audio formats and the type of sound file that we are required to deliver to the different digital music services we distribute to.

There are many different options of qualities within WAV and FLAC, however we strongly suggest you stick to these:


48 kHz · 24/16-bit

44.1 kHz · 24/16-bit


48 kHz · 24/16-bit

44.1 kHz · 24/16-bit

(32-bit, floating point and higher hertz is likely to cause issues.)

Reformatting files to WAV or FLAC

If you have your recordings in another format, then you will need to reformat these to WAV or FLAC in order to upload them on the Record Union website.

There are many different ways of doing this but below we outline 2 of the most straightforward ones.

Using iTunes

iTunes enable you to reformat audio files to and from a number of different file types, here is a handy guide which explains how to do this.

Using Audacity

If you do not have iTunes installed, then you can also use a free audio program called Audacity. Simply download and install the program, open the sound file and click "File" and then "Export". You will then be able to specify the correct format.

– If you don't have iTunes or Audacity installed, you can use an online converter such as:


When reformatting audio files its always important to listen through the newly created file carefully. There is always a small risk that the audio track becomes damaged or the levels become altered. Listening through to the track will enable you to detect this.

We also strongly suggest not to reformat files from a lesser quality sound type such as MP3 as this this will not result in optimal sound quality. The higher the quality of the sound file your reformat from the better.
