How to Make an AI Cover Song (Step by Step)

The quality of your source audio has a bigger impact on the final cover than most people expect. Here's what you ought to consider:.

Most commercial tracks don't need this step, since typically the source audio is already clean and well-produced. Where there can be some issues is with older, compressed, or live recordings. If using your own produced work, perhaps an untreated recording environment is introducing some issues. This is important to clean up beforehand, because reverb and background noise within the source will carry through the conversion and make for some awkward results in the final mix. Cleaning the audio before feeding it to a cover tool is often wiser than trying to fix it afterward.

Recording environments have a much larger impact on AI voice conversion quality than bitrate will. A clean recording at 128kbps or 320kbps will always outperform a noisy recording. If you are comparing two otherwise identical recordings, then a higher bitrate generally preserves more vocal detail, but the improvement is modest compared to the degradation caused by an untreated environment.

The voice model you pick matters as much as the song itself. Whether it’s genre, register, wanting a celebrity voice, or something original, these all affect whether you get the result you’re truly aiming for or not.

What to think about: A voice that sounds convincing on a rap track will fall flat on a pop ballad. A breathy indie vocal model applied to a drill beat sounds wrong immediately, even if the conversion itself is technically clean.

Genre and register first: Match the vocal characteristics of the model to the style of the song. Rap and hip-hop need delivery and cadence over pitch range. Pop needs brightness and the ability to carry a hook. R&B and soul need warmth and texture. Lo-fi and indie sit better with breathy, imperfect voices than powerful ones. If you're making a character or viral cover, the voice recognition is the whole point. Cartman covering a drill track works because the contrast is the joke.

Celebrity-inspired models vs originals: Celebrity models carry built-in recognition. If someone hears a Drake voice model on a song, they know what they're hearing. That recognition is part of why viral covers work. Originals built for music production, like the Lalals library of 25+ original voices, give you something that doesn't carry any artist association. Useful when you want the cover to stand on its own identity rather than lean on the cultural reference.

Library size vs curation: Musicfy has 100,000+ models. Jammable has 50,000+ community-trained models. Lalals itself has 1,000+ curated voices continually being updated and improved. It’s worth noting that bigger isn't always better. A well-trained and curated set of models will typically outperform a poorly trained one from a massive community library. If you end up using a community library, be sure to check how many versions of the voice exist, and then listen to samples before committing. Often these types of models can get you excited with their title, just for you to end up disappointed once you listen to the samples.

Using your own voice: If you want the cover to sound to be your own voice model rather than an original or celebrity, you’re in luck because most platforms let you train a custom one if you can supply it with enough training data of your voice. Lalals itself is a platform that supports voice cloning. Kits AI has three tiers of cloning from instant to professional; Musicfy includes two custom model slots on Starter; and Jammable can train a model from around ten minutes of audio in under fifteen minutes (though quality may vary). The quality of the clone depends heavily on the quality of the recording you train it on. A clean, dry vocal with no background noise produces a significantly more realistic model than a phone recording in a noisy room.

A few settings before you hit generate can make a significant difference to the output quality, especially if the source vocal and target voice are in different registers.

Pitch correction. Most platforms apply some degree of pitch correction automatically. For rap and spoken-word delivery this usually works well. For melodic singing, especially runs and melisma in R&B, it can smooth out too aggressively and flatten the performance. If the platform gives you a pitch correction intensity setting, start lower than you think you need.

Pitch shifting. This is separate from pitch correction. If you're applying a female voice model to a song with a male lead vocal, the register mismatch will produce an unnatural result at default settings. Raising the pitch of the input to sit closer to the target voice's natural range before conversion produces a significantly cleaner output. The same applies in reverse: male model on a female lead, shift the pitch down.

Conversion strength. Higher conversion gives you more of the target voice but can introduce artifacts, especially on complex melodic passages. Lower conversion preserves more of the original vocal character. For most covers a setting in the middle range works. For character voices where the transformation needs to be obvious, push it higher.

Most AI covers need at least a light polish pass before they're ready. This is the step most people skip and the reason a lot of covers sound close but not quite there.

What to think about If there is any room tone or background noise left in the converted vocal, it will sit awkwardly against the instrumental when you mix them back together. Run a de-reverb pass first, then de-noise.

Mastering. Lalals mastering tool is powerful and does more than play with an audio’s loudness. Mastering enhances what's already there, but it can't fix a mix that's already pushed too hard, so a clean track source is important. The tool allows you yo choose a style that fits the genre. Such as “Warm” for soul, R&B, and lo-fi; “Bright” for pop and EDM; “Punch” for hip-hop and beats; And “Wide” for anything that needs more space. If you want your cover to enhance a specific type of energy, you can even paste a YouTube link as a reference track and the tool will align the tone and loudness to it.

WAV vs MP3. Export in WAV for full quality. MP3 at 320kbps is fine for most streaming and social platforms if file size is a concern.

Copyright and AI covers. Posting a cover of a commercially released song involves the underlying composition copyright regardless of the AI tools used. Most streaming platforms require a mechanical license for cover uploads. Services like DistroKid handle this automatically for a fee. TikTok and YouTube use Content ID systems that may flag AI covers of popular songs. On YouTube this typically results in the rights holder monetizing your video rather than it being taken down. On TikTok, flagged content may be muted. Knowing this before you post avoids surprises.

Commercial use from the platform. Lalals requires Plus plan or above. Musicfy requires Starter or above. Jammable covers commercial use from the Basic plan. Music Creator AI requires an annual plan regardless of tier. Posting a cover generated on a free tier to a monetized channel is the kind of thing that causes problems later.
