Mixing and mastering: the difference
A guide to distinguishing work on individual tracks from processing a finished mix.

Mixing organizes the relationship between tracks. Mastering works on the final result. Separating a recording into stems can help you study its elements, but does not recover the original session.
Practice works better when you know what you want to hear. Before changing controls, choose a goal: learn an entrance, follow a progression or prepare your own performance. Audio and charts can help you work toward that goal from two perspectives.
Understand the process before you begin
Each stage answers a different question.
Before processing audio, separate arrangement, mixing and mastering decisions. Changing an entrance or removing an instrument changes the performance; balancing tracks is mixing work. Processing the finished mix comes later.
Stems are a listening and analysis tool. They do not replace the original recording or recover every detail of the studio session. Compare what you hear with the complete mix and note what needs review.
Step by step: prepare your song
Mixing: relationships between tracks.
Level, panning, EQ and dynamics help arrangement elements work together.
Mastering: the mix as a whole.
The presentation of finished audio is reviewed with tools and criteria suited to distribution.
Analysis: understand before deciding.
Use stems and charts to study a reference and document the arrangement. Mix and master with dedicated tools.
Start with a short passage. Alternate between the isolated part and the complete song to check how what you are learning fits together.
From audio to an editable chart
Listening to instruments helps you understand a performance. A chart documents its structure: chords, measures, key and sections. LeedSheet AI proposes a first version from your audio so you can review it with your own musical judgment.

- Review the chords while listening to the passage.
- Adapt the chart key to your version.
- Add the notes and cues you need to remember.
- Export a PDF to take to rehearsal.
How to review your result
Listen with headphones and check passages where several instruments overlap. Effects, backing vocals and sounds sharing frequencies can leave remnants in separated tracks. A complete first listen helps you decide whether the material suits your goal.
Also review the chart musically: check chord changes and section entrances. If detection differs from what you hear, correct the result before sharing it with your band. AI provides a starting point; you define the final version.
