Free mastering demo for new clients

Upload your unmastered track and we will give you a free mastering taster of what the final master will sound like.

This is completely free for stereo mastering – or you can try the stem mastering option for a very reduced price simply by purchasing a couple of stems to go with your free mastering demo order.

If you have any reference tracks you would like us to emulate the tone and feel of, you can upload them along with your tracks (clearly marking them as the reference file).

Please see our preparing your files page before uploading for the best end result (in brief = remove any limiter from the master out, check the waveform isn’t clipping and send high quality .wav or.aif files).

We will usually do your free taster within a day or 2, but please understand we must prioritise pre-paid work.
