Find what needs work in your demo.

SIGNR helps electronic music producers check a track before sending it out. It measures your audio, compares it with a genre reference and suggests labels to explore. The report combines those measurements with feedback to help you decide what to change and what to leave alone.

Yes. Upload a track and you get your technical readiness verdict and key measurements, no card required. A one-time €9 purchase unlocks the full report and includes one revision of the same track.

The free preview shows your track’s technical readiness and key measurements. The full report adds label matches with the reasoning behind each one, verified demo routes where available, next steps where your track needs them, the deeper mix diagnostics and a downloadable PDF.

Around 30 to 60 seconds from upload to your on-screen read.

Yes. There is a full live example report at /example, built from a real track that reads as Submission-ready, with Revealed Recordings and Spinnin' among its top directional matches.

You can run the free analysis and see your technical readiness verdict and key measurements first. A one-time €9 purchase unlocks the full report and includes one revision of the same track.

SIGNR was built by Daan Romers, known as DJ Dannic, a touring DJ and producer, from years on both sides of the demo inbox.

A WAV or an MP3, up to ten minutes. A WAV must be uncompressed PCM, 16 or 24 bit, mono or stereo, 44.1 or 48 kHz, up to 180 MiB. An MP3 can be up to 20 MiB; export at 320 kbps for the most accurate analysis.

For an MP3, yes. A clean 320 kbps MP3 preserves enough detail for the measurements SIGNR runs. Lower bitrates lose high-frequency detail, so avoid anything below 320 for a submission read. A WAV has no bitrate to worry about.

Either works. A WAV is the exported master itself, so true peak and the top octave are measured without encoding in between. A 320 kbps MP3 carries enough for the loudness, balance and structure measurements and uploads faster.

Not artistically. SIGNR never tells you a track is good, and it does not rate emotion or creativity. Your report has three layers. The measurements come from your audio: loudness, true peak, frequency balance, stereo, arrangement. The comparisons are calculated from those numbers against label catalogues: reference match and label fit. Release cadence sits next to them but is counted from a label's own release history, not from your track. The craft scores and the overall score are assessments: a language model reads the measurements and rates mixdown, arrangement, sound design, production and label readiness on a 1 to 10 scale. Informed by the measurements, but still a judgement, and labelled as one.

No. SIGNR measures your audio, it does not listen like a person. The interpretation layer frames those measurements with A&R experience, but every claim traces back to a measurement or a documented source.

Yes. The analysis covers the full arrangement, including how energy and structure move across sections, not just the intro.

Readiness is how close your track measures to release standard for its genre, from Not ready through to Submission-ready. It reflects production and technical fit, not a prediction that any label will sign it.

Mixdown Quality, Arrangement, Sound Design, Production Level, and Label Readiness. These are the same things an A&R checks in the first 30 seconds.

Not star ratings, and not all the same kind of number. Loudness, true peak, frequency balance and stereo are measured from your file. Reference match and label fit are calculated from those measurements against real catalogues. Release cadence is counted from a label's release history and says nothing about your audio. The five craft scores and the overall score are assessments: a language model turns the measurements into a 1 to 10 rating. That last layer is a judgement, so treat it as one. The measured numbers underneath it do not move.

No. SIGNR does not detect or flag whether music is AI-generated. It only measures the audio you upload.

No. SIGNR does not detect copyright infringement or sample clearance. That remains your responsibility before submitting.

Your report leads with a readiness verdict, from Not ready to Submission-ready, alongside an overall score. Work on your top blocker first, and note that SIGNR also flags what not to over-fix so you stop polishing what is already fine.

Around -7 to -9 integrated LUFS. These are club and Beatport submission targets, not streaming targets.

Around -8 to -10 integrated LUFS. Submit at that level rather than mastering to a streaming target.

Roughly -6 to -8 integrated LUFS. Louder is not the goal, competitive for the genre is.

Big-room masters sit at the loud, competitive end. Rather than chase a single number, upload your track and SIGNR measures your actual loudness against the relevant catalogue.

Upload it and SIGNR measures your integrated loudness and compares it to the genre reference, so you get a real answer. Remember these are club and Beatport levels, not the -14 LUFS streaming targets.

Often the master sits below the genre's competitive loudness range, or dynamics and low-end balance are eating headroom. SIGNR measures where your loudness and balance land versus real releases so you can see the gap.

LUFS measures perceived loudness across the track, while true peak measures the highest instantaneous level the signal reaches. SIGNR flags a true peak above +1.0 dBTP on a WAV as a listening check: listen to the master and an encoded version, and lower the ceiling if you hear distortion. On an MP3 the reading cannot show your master's peak.

Yes. The verdict, measurements, next steps and what to leave alone are about the track itself, so they apply whether you send it to a label or release it yourself. Label matches and demo routes are there when you also want to pitch it.

There is no general rule. When a label's own A&R sources say they look for a body of work, your report tells you for that label and links the source.

Label fit reflects genre overlap and tempo lane. Release research and available A&R evidence add context. Sonic similarity is a separate comparison with a smaller calibrated reference set. None of these predicts a signing.

Yes. Genre informs the reference used to interpret mix balance and other production signals. The report identifies which checks were possible with your source file.

100+ independent label profiles for label direction, informed by release research and available A&R evidence. Verified demo routes and calibrated sonic references are separate, smaller sets.

Use the label’s current official submission route and requested file or link format. Identify your track clearly, explain why it fits, and check the link permissions before sending.

Rank labels by how your sound fits their catalogue, not by prestige. SIGNR's label routing surfaces directional matches from measured audio, and the playbook adds a routing decision tree.

Amateur, muddy or dated production, a weak or generic kick in the opening bars, or an unclear genre identity. An A&R decides whether to keep listening within 15 to 30 seconds.

Use whichever route the label currently specifies. A public contact address is not automatically a demo inbox. Follow the form or email instructions, including file format, rights and number of tracks.

It depends on your genre and format: intro windows vary, and a radio edit is different from a club mix. SIGNR measures your intro against your genre's expected window and flags whether it reads as short, in range, or long, rather than applying one blanket rule.

The first sound sets the quality ceiling, the genre and energy should be clear by 15 seconds, and a teased hook by 30 gives a reason to keep listening. A firm, confident kick is your handshake.

Your €9 purchase includes one full report and one revision of the same track. Make changes, upload the updated version once, and compare both reports. There is no extra payment for that revision and no subscription. Check the offer for current revision-upload availability.

One updated version of the same track, measured in the same genre. Upload a changed file from the original report and compare both versions. It is not a second unrelated track. A revision cannot itself be revised using the same right.

Your purchase gives you one full-report unlock. The included revision is linked to the first report you unlock with that purchase. Purchases made directly from a report attach the revision to that report.

No. Packs provide separate full reports. Pack credits and promotional credits do not create revision rights. The included revision comes with a new €9 single-report purchase.

3 Reports is €19 for three separate full reports. Use them on different tracks or on more versions of one track.

5 Reports is €29 for five separate full reports, for a set of tracks you are preparing, such as an EP.

Credits from a pack are yours to use across your tracks. Each analysis draws one credit from the pack you bought.

Reach out through the contact page if something went wrong with your purchase and we will look at it. The free preview exists so you can see the tool before you spend anything.

No. SIGNR is fully independent and is not affiliated with, sponsored by, or endorsed by any label mentioned. Label profiles are built from publicly available release analysis and industry research.

No. Your audio is analysed and then deleted. We keep the report and the account data needed to provide the service, nothing more.

Your audio file is not sent to the report-writing AI. Measurements and the track details you provide are sent to Anthropic to generate your report. Anthropic says commercial API inputs and outputs are not used for training by default, with exceptions for feedback or permission to use data. Account-specific permissions and any manual reuse of SIGNR data have not been verified, so we cannot give an unconditional no-training promise for every data flow.

No, and it never claims to. SIGNR gives measured, directional feedback so your track does not get killed for reasons you could have fixed. The decision is always the label's.

Then you might be right. Treat the report as a measured second opinion, change only what you agree with, and re-analyse to check the result.
