How to Prepare Your Track

Quick Checklist Before You Master

• Avoid unnecessary heavy limiting
• Export a lossless file when possible
• Listen to the exact file you plan to upload

What Mastering Can — and Cannot — Fix

Mastering works on the finished stereo mix. It can refine the overall presentation of a track, but it is not a reliable repair tool for creative or source-level problems.

1. Choose the AI Track Worth Mastering

If you generated several versions from the same prompt, listen to each one from beginning to end before choosing a favourite. A strong hook matters, but so do transitions, vocal delivery, development, and the ending.

Ask yourself whether the track maintains a consistent mood, whether the lyrics are understandable where they need to be, whether instruments disappear or jump out unexpectedly, and whether the song develops naturally rather than simply repeating.

Write down the time of any problem you hear. If one version has a great chorus but a noticeably broken verse, see whether you can regenerate or edit that section before mastering. Mastering can refine the overall sound, but it cannot reliably rewrite a lyric, correct an unnatural performance, or rebuild a weak arrangement.

2. Listen for AI Audio Artifacts

AI-generated music can contain small flaws that are easy to miss during a quick preview. A cymbal may sound grainy, a vocal consonant may smear, or the texture of the background may change unexpectedly between sections.

Listen once on headphones and once through ordinary speakers. Pay particular attention to the start and end of the track, where clicks, abrupt cuts, and unfinished reverb tails are more noticeable. Check transitions between verses, choruses, and instrumental sections as well.

If an artifact is built into the generated audio, making the track louder can make it more obvious. Fix the source or choose another generation when possible. If you only have a finished stereo file, make small edits carefully and re-check the surrounding section afterward.

3. Fix Arrangement and Mix Problems Before Mastering

Before adjusting loudness or final polish, make sure the song itself feels complete. Does the intro reach the main idea quickly enough? Is the chorus repeated the right number of times? Does the ending resolve, fade naturally, or stop at a deliberate point?

These choices matter especially for short videos and ads. A track designed to sit under narration may need more open space. A song intended to stand alone can support a fuller arrangement. If you plan to use several excerpts from the same track, identify those sections before making final edits.

Then check the balance. If you can edit separate vocals and instruments, settle that relationship before mastering. Make sure the lead vocal is clear without overpowering the music, the kick and bass do not mask one another, and bright percussion adds energy without becoming harsh.

If you only have a stereo export, avoid heavy processing to compensate for one isolated problem. Boosting the high end to reveal a quiet vocal can also make cymbals harsh. When one element is wrong throughout the song, returning to the generation or edit stage is often the better solution.

4. Leave Headroom for AI Mastering

It can be tempting to make a track as loud as possible before export. That may leave too little room for further processing, especially if a limiter has already flattened the loudest moments.

There is no single universal headroom target for every mastering service. The practical goal is a clean file that does not clip and still retains useful dynamics. If a service gives specific upload guidance, follow it rather than forcing the track to match a generic number.

If the generated track is already heavily compressed or limited, simply turning it down will prevent additional clipping but will not restore dynamics that have already been lost. If the song sounds tiring or the chorus has little extra impact, compare it with another generation before moving on.

5. Export the Best File for Mastering

For online audio mastering, use the highest-quality file available from your creation or editing workflow. A lossless WAV or AIFF is generally preferable to an MP3 when you have the choice.

Keep the track at its native sample rate unless the mastering service asks for something specific. Do not convert an MP3 to WAV simply to make the file larger; the conversion cannot restore information that was already removed by compression.

Before uploading, listen to the exact exported file. Confirm that it contains the full song, starts cleanly, and allows the final note or reverb tail to finish naturally.

Use a clear filename such as Song-Title_Unmastered-Mix_v2.wav. If you are working with several generations, keep the file together with the prompt, version notes, and edit decisions so you can trace which source produced the final master.

6. Decide What You Want the Master to Improve

“Make it sound professional” is a useful ambition, but a more specific goal will help you judge the result. A background track for a spoken video may need warmth without crowding the voice. A dance track may need a solid low end that still translates to smaller speakers. An acoustic song may benefit from keeping its quieter moments intact.

Choose one or two reference tracks with a similar style and purpose. Listen for broad qualities such as brightness, bass weight, vocal presence, and overall energy rather than expecting your AI-generated song to sound identical.

Compare the references and your own track at roughly similar listening levels so volume alone does not influence your decision.

7. Check the Master in Real Listening Conditions

After mastering, compare the new file with the original at similar volumes. Is the vocal clearer? Does the chorus have more impact? Did any cymbals become sharp or bass notes become muddy?

Then listen on the devices your audience is likely to use: headphones, a phone speaker, laptop speakers, or a car system. The goal is not for the track to sound identical everywhere. The goal is for its main musical idea to remain clear and balanced across common listening environments.

If you hear a serious problem, revisit the source track or mix before trying repeated rounds of mastering. Often the most effective change is a cleaner generation, a better edit, or a small balance adjustment earlier in the workflow.

From AI Generation to a Release-Ready Track

AI music generation can get you surprisingly close to a finished song, but mastering works best when the source track is already clean, balanced, and intentional.

Treat mastering as the final stage, not a repair tool. Choose the strongest generation, remove obvious problems, export the best source file you have, and then use mastering to refine the result for real-world listening and release.
