Professional Online Mastering

Mastering is the final stage of production, where a mixed track is refined and optimized for CD, digital distribution, and streaming.
It balances tone and loudness, brings sonic consistency to the work, adjusts spacing between songs, and prepares the final delivery formats for pressing plants or digital platforms (DDP, CD-DA, WAV).

At Crunch Studio, our experienced mastering engineers draw on a wide range of production experience to bring greater clarity, impact, and depth to your music.
We handle a wide range of genres with care and precision, from singer-songwriter to pop, rock, and metal.

We offer everything from single-track mastering (tone and loudness adjustment with WAV delivery) to album and EP mastering (tone, loudness, spacing, PQ editing, and master disc delivery).
We also offer Stem Mastering and Mix Feedback as additional options.

Crunch Studio’s online mastering service is ideal for remote projects, helping turn your mixes into a finished master that reflects exactly what you want to hear.

About Stem Mastering

Stem Mastering is recommended for artists who feel, “I handled the mix myself, but I’m not fully confident in the mastering,” or “I want the mastering process to be more active and flexible.”

Instead of submitting a standard stereo mix (2-mix), you provide the material divided into instrument groups, and the mastering engineer makes detailed adjustments to each stem before carrying out the final mastering.

With standard stereo mastering, for example, reducing the low-mid range of the drums also affects the low-mid range of other instruments, which often requires compromise. With stem mastering, however, it becomes possible to reduce the low-mid only on the drum stem while enhancing it on the guitar stem, allowing for much more flexible and precise control.

This makes the mastering process more active, more flexible, and more precise.
If your budget allows, we highly recommend Stem Mastering as an additional option.

About Mix Feedback

Mix Feedback is recommended for artists who feel, “I handled the mix myself, but I’m not fully confident in the result,” “I want to improve my mix before mastering,” or “I’d like an objective third-party perspective.”

Before the actual mastering begins, the engineer listens to your mix and provides specific feedback in report form, including concrete suggestions for improvement as well as overall impressions.

Mastering delivers its full value when the mix is already in good shape. If you want to refine your mix as much as possible before mastering, this option is a highly effective way to get objective, professional feedback.
