Do you need mastering?

For most official releases, yes — you need mastering. For a rough demo sent to a friend, often no. The real question is whether your mix is ready, because mastering cannot fix a weak balance.

You need mastering if

• You are releasing on Spotify, Apple Music, Bandcamp, etc.
• You want competitive loudness and tone in your genre
• You need clean formats and QC before distribution
• You care how the track sounds on phone, car and earbuds
• You are releasing an EP/album and want consistent level

Mastering alone may be enough if

• You have a strong approved stereo mix
• Balance, vocal level and low end already work everywhere
• You only need final polish and loudness

Send one WAV with headroom: what files do you need for mastering.

You need mixing first (not only mastering) if

• Vocals are buried or low end is messy
• You only have stems, not a finished mix
• The track feels small or harsh on multiple speakers

→ Mixing vs mastering

You might skip mastering (rare) if

• Private scratch demo, not public
• Label/studio already delivered a mastered file for release
• You are explicitly A/B testing mix versions only

Even strong self-mixers often master for translation and QC.
