Worth knowing
Suno to SRT, Udio to SRT, and AI song subtitles
If you searched for "Suno to SRT," "Udio to SRT," or "download captions from Suno," this is the workflow: copy your generated lyrics, download the MP3, upload both to LyricTime, then export a timed SRT, LRC, or VTT file.
That gives you lyrics with timestamps for AI song subtitles, lyric videos, CapCut edits, karaoke files, or any other workflow that needs the words lined up with the vocal.
The process
How it works — the recommended Suno/Udio workflow
01
Copy the lyrics
straight from Suno or Udio's lyric field — you already have the exact words.
02
Download the MP3
of your generated song. MP3 export is available on both platforms' free tiers — you don't need a paid plan just to get the audio file for this workflow.
03
Upload to LyricTime and choose "Upload MP3 + paste lyrics."
Paste in the lyrics you copied — this is the step that makes this workflow more reliable than letting LyricTime transcribe from scratch.
04
Let LyricTime time the lyrics to the vocal.
Because the words are already known, it only needs to solve timing, not guess words too.
05
Review and export.
Check timing in Timeline mode, clean up any line breaks in Blocks mode, then export SRT, LRC, or VTT depending on where the file is headed next.
Worth knowing
Before you paste: check the vocal actually matches your lyrics
This is worth knowing before you start, because it's a real and fairly common Suno/Udio quirk: the AI doesn't always sing exactly what's in the lyrics box. Sometimes it mumbles, skips a line, repeats a section, or — especially after extending a clip — drifts into completely different words for a stretch of the song. Creators sometimes call this "lyric hallucination," and it's a known limitation of AI vocal generation, not something specific to LyricTime.
Why this matters here: LyricTime's "Upload MP3 + paste lyrics" option times the words you give it against the vocal — it doesn't independently fact-check whether those are the words actually being sung. If you paste your official Suno or Udio lyrics but the vocal genuinely diverged from them somewhere in the song, the synced file will confidently show your intended lyrics timed to audio that's actually singing something else.
The fix is simple: before you paste your lyrics into LyricTime, listen to your generated song while reading along with the lyrics text, checking that what you hear actually matches what's on the page — especially around extended sections or fast/dense lines, which is where this tends to happen. If a section drifted, you've got two good options — fix it at the source in Suno or Udio (most have a way to regenerate or replace just that section without redoing the whole song), or edit your pasted lyrics to match what's actually sung before uploading to LyricTime, so the timing lines up with the real vocal rather than the original intent.

The main thing to know
Choosing "Upload MP3 + paste lyrics" here is usually the right call, and it's worth being explicit about why: you have the lyrics from the generation step, so there's normally no reason to make LyricTime guess words it doesn't need to guess. This generally produces a more reliable result than transcribing from scratch, especially on AI vocals, which can have unusual phrasing, pacing, or production effects that make pure transcription harder than a typical studio vocal — as long as the vocal actually sings what's in your lyrics box (see above).
Expected result
A quick review still matters
To be fair to "Upload MP3 only" too: Suno and Udio vocals are often clean and clearly mixed by AI-generation standards, which actually helps transcription accuracy when you do need it. But pasting the lyrics in is still the better choice whenever you have them, simply because it's solving one problem instead of two — and because the words are already correct, timing usually comes out very close to spot-on. Even then, it's worth a quick scan through the editor — fast or unusually phrased AI vocal deliveries can occasionally need a small timing nudge on a line or two, which Blocks mode's 0.1-second adjustments handle well.
Tips
Common mistakes and what to do instead
Don't skip pasting in your lyrics and default to "Upload MP3 only" — if you already have the words and the vocal genuinely matches them, pasting will almost always give you a better result.
Listen to your generated song while reading along with the lyrics text before pasting them in, especially if you extended the song or it has fast/dense sections — confirm what you hear actually matches what's on the page rather than assuming it does.
Copy lyrics directly from Suno or Udio rather than retyping from memory, to avoid small wording mismatches that can affect timing accuracy.
If your AI song has ad-libs or production tags not meant to be sung — stage directions or structure tags like [Chorus] some tools include in the lyrics field — strip those out of the pasted lyrics before uploading. Only the words actually sung should go in.
If a non-word ad-lib sound (a wordless "uh," a vocal run, harmonizing) doesn't show up in your timed lyrics, that's expected — actual words come through, but non-word vocal sounds generally don't get transcribed since there's no word to capture.
Practical details
Before you upload
How long does processing take?
Most songs are done in well under a minute — often around 25 seconds in practice. To be safe, plan for up to 30-60 seconds depending on the song.
Is there a file size limit?
Yes — uploads are capped at 15MB per file. A typical full-length MP3 at standard quality comes in well under that.
What languages does this support?
Eight languages are officially supported: English, German, Spanish, French, Italian, Portuguese, Japanese, and Korean. Outside of those, results aren't guaranteed, though other languages have worked for some users in practice.
FAQ
Got a question?
Should I use "Upload MP3 only" or paste my lyrics in for a Suno or Udio song?+
Paste them in, as long as you've listened along while reading the lyrics text and confirmed they match what's actually sung — see the note above about checking before you upload. If the vocal drifted from the lyrics anywhere in the song, "Upload MP3 only" or a corrected paste is the safer choice for that section.
Why would the lyrics I paste not match what's actually sung?+
Suno and Udio sometimes generate a vocal that mumbles, skips, repeats, or drifts from the lyrics you provided — this is a known AI vocal generation limitation often called "lyric hallucination," and it shows up more after extending a clip or on fast, dense lines. It's worth listening along while reading the lyrics before pasting them into LyricTime, since LyricTime times whatever words you give it rather than checking them against the vocal itself.
Where do I get the MP3 from Suno or Udio?+
Download it directly from the platform after generating your song — MP3 export is available on both platforms' free tiers.
Can I turn a Suno or Udio song into an SRT file?+
Yes. Copy the lyrics from Suno or Udio, download the MP3, upload both to LyricTime, then export SRT for captions, lyric videos, YouTube, or CapCut. You can also export LRC or VTT from the same synced project.
Can I download captions from Suno directly?+
Suno can show lyrics in generated videos, but if you need a separate editable subtitle file, use LyricTime to create your own SRT, LRC, or VTT from the song audio and lyrics.
Will it handle unusual AI vocal phrasing okay?+
Generally yes when you've pasted the lyrics in, since it's only solving timing. Occasional small adjustments may still be needed for unusual pacing — Blocks mode's precise nudge controls make that quick.
What should I do with non-lyric text in the Suno or Udio output, like section tags?+
Strip those out before pasting in — only include the actual sung or rapped words, not structure labels like [Verse] or [Chorus].
Can I use this to make a lyric video for my AI song?+
Yes — LyricTime creates timed subtitles and lyrics for AI-generated songs from Suno, Udio, and similar tools. Export SRT and bring it into your video editor, or import it directly in CapCut. See our YouTube lyrics page or our CapCut guide for those specific workflows.
Can I turn my Suno or Udio song into a karaoke version?+
Yes, with one extra step: you'll need an instrumental with the vocals removed first. Suno has a built-in "Get Stems" feature for this — find the song in your Library, open More Actions, and choose Get Stems to extract a vocals + instrumental split. Then time your lyrics with LyricTime as usual and export LRC. See our karaoke maker page for the full workflow.
