How do I export my mix for Mastering Only service?

1. Keep the bit rate and sample rate consistent with your DAW settings; 24-bit 44.1 kHz wav or aif is standard.

2. Export your mix with all plugins enabled, including those on the master bus; we’ll use this as a reference.
3. Now export again, but disable the master bus plugins and ensure the mix doesn’t clip—adjust the master fader if needed. We’ll use this for Mastering
4. If all you have is an MP3, we can still work with it it using advanced sound restoration tools.

What is the turnaround time for Mastering?

Standard delivery is 4-5 business days. A 2-business-day Rush Service is also available.

What is the difference between normal Stereo Mastering and Stem Mastering?

Stereo Mastering is the traditional approach where we work with your finished mix, delivered as a single stereo track. We clean up and enhance this track through the mastering process. On the other hand, Stem Mastering allows for more flexibility. In this case, you provide multiple stems, each containing a group of instruments (like drums, vocals, bass, etc.) with their effects. We can then retouch and rebalance these individual stems before mastering. Note that Stem Mastering isn’t for raw vocals or instruments; those should be properly mixed before the mastering stage.

What is the Apple Digital Master Option?

We are proud certified providers of Apple Digital Masters. Choosing this option means you’ll receive an additional master tailored for high-quality digital audio on streaming services, Apple Music, and the iTunes Store. By following Apple’s precise guidelines, we control loudness and enhance dynamic range, ensuring a superior listening experience across all devices and especially on streaming platforms.

Do you offer mastering for vinyl?

While we don’t cut lathe, we do offer vinyl-compatible masters. Mastering for vinyl involves some unique considerations. For example, vinyl is not friendly to stereo bass due to the physics of how it’s cut. The low end usually needs to be collapsed into mono. Additionally, vinyl prefers a bit more dynamic range, so overly loud masters aren’t ideal. If you want your mastering to be vinyl compatible please send us a message about it when you upload your material.

What is the Valve Option for Mastering?

Selecting the Valve Option allows us to master your music through our high-spec, tube-based analogue mastering chain. This setup includes renowned boutique processors like the Thermionic Culture Fat Bustard and the Phoenix Mastering Compressor, along with the acclaimed Shadow Hills Mastering Compressor. This specialized gear enhances your sound, making it denser, more impactful, and sophisticated.

What is the Tape Option?

With the Tape Option, we route your music through our Studer A-80 Master Tape Recorder as part of the mastering process. This recorder is renowned for being one of the best-sounding recorders ever built. It delivers that silky sound that characterizes pre-2000s music. If you’re looking to add a touch of retro to your music, this is an excellent choice.


What is the difference between Mixing and Mastering?

Mixing involves balancing separate channels for each instrument—like bass, drums, vocals, guitars etc.—into a cohesive stereo track. This involves working with a mixer to blend multiple audio files. Mastering, on the other hand, focuses on optimizing that final stereo file. It involves applying the finishing touches such as EQ, loudness, and compression to ensure the track is ready for listeners. Simply put, mixing deals with multiple audio files, while mastering refines a single stereo pair.

What is the turnaround time for Mix and Mastering?

Our standard turnaround for Mix and Mastering is 7-10 business days. Need it faster? A 2-business day Rush Service is available.

What is the Valve Option for Mix & Mastering?

Choosing the Valve Option lets us leverage the full capabilities of our Thermionic Culture Fat Bustard 14CH Tube Summing Mixer. We separate mix groups through multiple outputs from the converters, enhancing the sense of space in the mix. This setup also allows for precise control over the level of saturation, making your mix truly stand out. This option is highly popular and works well for most music styles, except for classical.

How to Prepare Your Music for Mix & Mastering?

1. Save a Reference Mix: Keep your current mix with all plugins.
2. Clean the Master Bus: Remove all plugins and make sure the mix doesn’t go into the red. Lower the master fader if needed.
3. Handle Plugins: Turn off all EQ and Compression. If you like your settings, send two versions of each file: one with effects (wet) and one without (dry). Both versions count as one track for our service.
4. Export Settings: Use the same Bit depth and sample rate as your recording session. If unsure, 24Bit 44.1Khz is standard.
