The workflow
From upload
to final delivery.
Streaming preview
Hear your track
at streaming loudness.
Each platform handles loudness its own way, and Bandcamp doesn't normalize at all. How much gain a service applies depends on its playback mode and the headroom in the master. Soneam previews those changes before the client approves, and you can also play the master through each codec. TikTok publishes no reference, so its target is an estimate. Actual playback depends on the service, settings and device.
- ✓ Spotify, Apple Music, YouTube, Tidal, Amazon, Deezer, TikTok and Bandcamp targets
- ✓ Preview the encoded audio: Ogg Vorbis at 96 kbps, AAC-LC 256 for Apple Music, Opus for YouTube
- ✓ A true-peak reading against each platform's ceiling. Check the reading alongside the audio
- ✓ Switch targets live during playback, with no re-render

Fair Loudness: compare versions at matched loudness
A louder version tends to sound better for that reason alone. Fair Loudness turns the louder one down to match the quieter one, on your screen and on the client's link. Matching only attenuates, so it won't boost into clipping or re-encode the audio.
Try Fair Loudness free, no signup →Mastering-grade metering, every version
Integrated LUFS, true peak, sample peak, loudness range (LRA), dynamic range and PLR/PSR, plus a loudness-over-time curve drawn right on the waveform. Measurements are calculated automatically for each version.
Lossless playback, checksum-verified delivery
Playback is lossless FLAC (a 32-bit float file plays as 24-bit). Every delivered file carries a SHA-256 checksum, so anyone can confirm the download is the file you uploaded.
checksum · download ≡ your upload
A record of every approval
Comments are for changes; approval is a separate step on one version. Each approval records who approved it and when, with the file's SHA-256 checksum. Add a password, or replace the link so the old URL stops working. Downloads are tracked.
After you share
See which versions
and sections were played.
Know whether the link was opened and the mix was played before you follow up, and which sections of each version were played. Select a section to highlight it on the waveform, then press play to hear that part. Comments and approvals for the version are on the same screen.
Visits is included on Pro and above. On Free, a 14-day trial starts when a client first plays audio through your review link. Records do not identify people or count repeat plays.

Soneam
Clients review and approve a specific version on one link. You can release the original files there and keep downloads locked until payment is confirmed. The payment lock works on every plan, including Free, and the money goes straight to you.

What engineers ask before they send their first review link.
Can I preview Spotify's loudness normalization before release?
Yes. Soneam approximates Spotify's loudness normalization so you and your client can preview the change before approval. Actual playback can vary with Spotify's settings and the listener's device. Try it with the free loudness tool, without an account. Try the free loudness tool →
How do I get a client to approve a final master?
Send one review link. Your client plays a lossless preview, leaves notes on the waveform, and presses Approve on the version they accept. Soneam records the name they enter, the time, the version and the file's SHA-256 checksum, and the record can be printed. The client needs no account. The record identifies the version and the details the reviewer supplied; it does not verify their identity.
How do I get paid before sending the final files?
Set a balance on the delivery. The files stay locked on the review link until it is paid: by card through your own Stripe account on Pro and above, which unlocks them automatically, or by bank transfer, PayPal or anything else, which you confirm with one click on any plan, including Free. The money goes straight to you. Soneam never holds client funds and takes no fee; Stripe charges its own processing fee on each card charge.
Do my clients need an account to review or approve?
No. You send a link, and your client plays the master, leaves feedback pinned to the waveform, and approves. There's no signup and nothing to install.
How does Soneam compare with Samply?
Both let clients listen and comment, and Samply can also unlock downloads after payment. In Soneam, clients can approve a specific version, and you can print the approval record. You can also preview the master at each streaming platform's loudness. Samply has a native iPhone app and gapless album playback, which Soneam does not. Soneam vs Samply, compared →
Is the playback actually lossless?
Soneam uses FLAC for review playback and keeps the original for delivery. Supported 16- and 24-bit lossless sources retain their decoded samples; 32-bit float is converted to 24-bit for preview. A delivery checksum lets you check the downloaded file separately from playback.
Can a client record the stream instead of paying?
Anything that plays in a browser can be recorded, and a lock does not change that. What it holds back is the delivery: the original files and stems, with their SHA-256 checksums, appear on the page only when you release them, and a release can stay locked until you confirm payment. You can password-protect the link. If it leaks, replace it and the old URL stops working.
What happens to my files if I stop paying?
Your plan changes to Free at the end of the paid period, and existing files and review links stay available. Free has no time limit. Files above the 5 GB Free allowance are retained for at least 12 months after the paid plan ends; after that, excess files may be removed following an email notice. On Free, released files have a 30-day download period, and you can release them again for another 30 days. What happens if I cancel →
