• 24bit .WAV – Streaming Master (96KHz or 48KHz)
  • 16bit .WAV – CD Master (44.1KHz)
  • 24bit .WAV – Video Master (48KHz)
  • .MP3 320kbps
  • DDPi format (if you provide us with ISRC codes and all essential metadata)

Instrumental and backing track masters will be delivered only if you provide us with the instrumental and backing track version of the mix. They will be of the same resolution as the streaming master. 

DDP image for physical CD distribution will only be delivered if you provide us with the following metadata:
– official title of the song / songs
– official title of the EP / LP / Album
– legal names of all songwriters (specified for each song)
– ISRC codes for each song

– UPC / EAN (if applicable)

Stereo / Stem Master

Stereo mastering is done to a stereo mix as its source. It can limit the possibilities to potentially re-shape the track. For example, if you need to increase the level of the drums, stereo mastering would also increase the level of every other element of the mix. The same rule applies to equalization, compression and all creative effects you might want to implement.

With stem mastering, all of these elements are accessible separately, so you can increase just the level of drums without changing the balance of other elements. It allows an engineer to process a single element of a song in isolation. Stem mastering can be as simple as having two stems (example: vocals and instrumental) or multiple stems (example: drums, bass, guitars, keys, vocals) allowing more flexibility and control.

Stem mastering allows an engineer to fix a problem that can occur in one element of the mix, without processing other elements. The engineer may not change every single stem, but the process gives them the option to do so if necessary.

For Stereo mastering you would be asked to deliver the following files:
– Full Mix (24bit .WAV file)
– Backing Track (24bit .WAV file)
– if you’d like to receive the backing track master.
– Instrumental (24bit .Wav file) 
– if you’d like to receive instrumental master.
 All files must not be hitting 0dB true peak. You should not have a limiter applied to the mix.

For Stem mastering you would be asked to deliver the following files (choose the applicable for your project):
– Drum stem (24bit .WAV file)
– Bass stem 
(24bit .WAV file)
– Guitar stem 
(24bit .WAV file)
– Keys / Synth stem 
(24bit .WAV file)
– Orchestral stem 
(24bit .WAV file)
– Backing Vocals stem 
(24bit .WAV file)
– Lead Vocal stem 
(24bit .WAV file)
All files must not be hitting 0dB true peak. Ideally, all stems summed up should also not hit 0dB true peak.

Alternatively, for stem mastering, you’re welcome to deliver only Instrumental stem and Vocals stem if you don’t need much work to be done on individual groups. (The pricing for stem mastering won’t change).


2 revisions are included within the price (This does not include new mixes).

Turnaround Time

Turnaround time generally depend on the amount of songs and whether you need stereo or stem mastering. It will extend if you hire us to master an EP or an Album.

Usually, we send the first pass of the master within a day. After we receive all files for the project and examine them, we are able to give better estimated turnaround time specifically for your song / EP / Album.
