Try ChangeLyric For Free

ChangeLyric is the only lyric swap platform with zero content filters. Upload any track, edit any lyrics, get back separated stems. The Overdub engine lets you change every lyric in a song in a single submission instead of working section by section. I built this as a production tool for producers who understand copyright and handle licensing responsibly.

Upload an MP3, label each section (verse, chorus, bridge, post chorus), and edit the lyrics in the editor. Submit your changes and Overdub generates a new vocal performance for the whole song. You get back a downloadable package with a lead vocal, backing vocal, original instrumental, a vocal bus, and the raw takes straight from the engine so you can comp them yourself in a DAW.

Overdub is the new section-aware bulk editor and is the default for most songs. Classic mode is the older inpainting engine and is still available via the toggle on the dashboard. For dense rap or rapid fire vocals (think 700+ word songs), Classic often wins. For pop and country with normal verse chorus structure, Overdub is roughly 10x more likely to return a usable result. You can run both and comp the best parts together in a DAW.

Section tags are how the engine understands which parts of the song share a melody and a vibe. If two sections have the same melodic idea, label them the same way (for example, both choruses should be labeled chorus) so the engine treats them as the same musical idea. If a section is mislabeled, fix it before you submit. The original transcription is a best guess and is often worth correcting.

If a section runs close to a minute or longer, split it in half. Use tags like verse 1.1 and verse 1.2 on both the original and edited columns. The tags between the two columns have to match exactly or you will get an error. Splitting long sections helps the engine handle them cleanly. Most songs do not need this, but if a verse feels too long, split it.

The preview is a scratch track, not the final. AI comping of vocals is genuinely hard, and the in-page preview is the engine's best automatic attempt to stitch the new takes into the original. Timing may be slightly off and edits may not be perfectly seamless. The real output is the download package: separated stems and raw takes that you can line up and comp manually in a DAW to get something significantly better than the preview.

You get a lead vocal, a backing vocal, the original instrumental, a vocal bus that combines the vocals from the original, and the raw takes generated by the engine. The raw takes give you maximum control as an editor. You can drop them into any DAW, line them up, swap between takes per line, and use side chain compression to duck the original where the new vocal sits.

Upload MP3 files up to 50MB. You get back a package containing separated stems that can be imported into any DAW.

Yes. The output stems work with Pro Tools, Logic Pro, Ableton Live, FL Studio, Cubase, Studio One, and any other DAW that imports audio files.

Yes. There are no content restrictions or censorship filters. Overdub supports lyrics with different word counts than the original. Put whatever you want in each line and the engine handles timing and placement. Smaller changes tend to produce more natural results, but full rewrites are fully supported.

Overdub is significantly simpler than the old section-by-section workflow. Upload, edit lyrics, submit, download the stems. This is still a professional tool though. You need DAW experience to comp and mix the output stems into a finished track. If you have never worked with vocal stems before, expect a learning curve. If you use a DAW daily, you will pick it up fast.

First-run processing takes a few minutes per song while the engine analyzes your track. Subsequent versions on the same song are typically faster. Processing continues in the background, so you can close the page and come back when it is done.

Three cases. First, spoken audio (use the Speech Changer instead, which is built for that). Second, very dense rap or rapid fire vocals with 700+ words. The Classic engine is usually a better fit. Third, structurally unusual songs (the joke is Bohemian Rhapsody). Overdub performs best on pop, country, and standard verse chorus verse chorus bridge chorus structures. If your song is one of these edge cases, run Classic too and comp the best parts together.

Usually not. Overdub is built to change lyrics in the same language as the original. Translating a song properly requires hiring a singer to create a new pilot vocal and then doing AI processing to make it sound like the original. It is genuinely hard to do well. Hire our team if you need help with select languages.

No. ChangeLyric has zero content moderation filters. No audio fingerprinting, no automated rejections, no false positives blocking your own productions. You decide what you have rights to modify. Users are responsible for understanding applicable copyright laws.

Credits are shared between the Overdub engine, Classic mode, and the V2 Horizon tool. Overdub costs 1 credit per 10-word chunk changed. Your credit balance resets each billing cycle.

No. Credits reset at the beginning of each billing cycle and do not carry over.

Yes. Cancel from your account dashboard at any time. You keep access through the end of your current billing period.

After downloading your stems, open them in a DAW and line up the raw takes by hand where the auto-comp missed. Use side chain compression on the original vocal bus, keyed by your new lead and backing tracks, to duck the original out when the new vocal sits. Run the comped vocal through the Voice Changer to smooth tonal differences. Pre-processing complex mixes with the Vocal Splitter before upload can also help. As a last polish, running the result through Suno's Cover feature can smooth lingering issues.

No AI vocal tool delivers perfect studio results yet, but Overdub's separated stems give you full control to EQ, compress, and mix the new vocals however you want. Overdub and Classic together give you a fast way to generate demo quality lyric changes. V2 Horizon is harder to use and more unpredictable, but provides closer vocal tone matching on solo vocals. The Voice Changer tool can further smooth solo vocals in many cases.

Yes. The Vocal Isolator separates vocals from instrumentals. The Vocal Splitter separates lead vocals from backing vocals. Both are included in your subscription and accessible from the dashboard.

Yes. New users get a 7-day free trial with enough credits to actually test Overdub on a real project. The trial requires a card on file so you have time to use the tool, see if it works for your song, and cancel before the trial ends if it is not the right fit. No charge until day 7.

The Overdub download contains many audio files a skilled producer can use to assemble a finished song. It requires editing in a DAW. If you do not want to do that yourself, our team has done over 600 orders and can handle it for you. Submit your lyrics through the service page and we will produce the audio.
