How to invite a client

1. Open the album you want to share.
2. Scroll to the "Clients" section at the top of the album page.
3. Enter the client's email address, first name, and last name.
4. Click "+ Add client".
5. Click "Send mail".
6. The client receives an email with their personal access code.
7. The email contains two links: one to open the album in the web player, and one to open it directly in the MixReview iOS app.
8. They sign in with their email and that code. No account needed.

What clients can and cannot do

Clients can:

• Listen to all mix variants (Stereo, Dolby Binaural, Apple Atmos)
• Switch between variants and track versions

Clients cannot:

• Download any audio file
• See other albums or projects
• Change any settings

Managing existing clients

Once a client has been added, their row shows the following actions:

• Rotate code: Generates a new access code and invalidates the old one. Use this if you want to block access without deleting the client entirely.
• Open in Mail: Opens a pre-filled draft in your local mail client (e.g. Apple Mail). The subject, login link, and access code are already filled in — you can add a personal message before sending.
• Send mail: Sends the invite email directly via MixReview. Shows Sending… → Sent ✓ as feedback. Use this for a quick resend without any customisation.
• Keep Informed: Toggle this on to automatically notify the client by email whenever you upload a new track or a new track version to this album. The button turns green (like the Batch Upload button) when active. Toggle it off to stop notifications for that client.
• Delete client: Removes the client and invalidates their code permanently.

File naming convention

MixReview detects the variant from keywords in the filename. The part before the last _-separated keyword becomes the track name:

How to batch upload

1. Open an album in your dashboard.
2. Click "Batch Upload" in the album.
3. Drag and drop your files onto the upload area. Or click it to open a file picker and select multiple files at once (⌘+A).
4. MixReview analyses the filenames and shows a preview of the assignment.
5. Review the bundles and click "Upload". Progress is shown per file.

How bundling works

After dropping your files, MixReview automatically groups them into track version bundles:

• Files with the same track name are automatically bundled into one track version, e.g. MySong_Stereo.wav and MySong_Binaural.wav become two variants of the same version.
• The variant (Stereo, Binaural, Apple Atmos Prerendered, Apple Atmos JOC) is detected automatically from the filename suffix.
• You can manually adjust the bundles before uploading. Drag files between bundles, or use the buttons to merge or split them.

Supported formats

Sorting tracks

Each track has Move track up and Move track down buttons in the top right corner of the track card. Use them to reorder tracks within the album. The order is reflected immediately for clients in the player.

Renaming and deleting

• Click the pencil icon next to a track name or mix version name to rename it inline.
• Use Delete track to remove a track and all its mix versions and variants permanently.
• Use Delete mixversion to remove a single mix version (and its variants) from a track.

Level settings

Different mix variants naturally have different loudness levels. Level settings let you compensate for this so clients always hear a fair, consistent comparison, without any variant sounding louder just because of its format.

Auto Level reads the measured LUFS (integrated loudness) of each variant, measured during upload via FFmpeg, and automatically calculates the gain needed to bring all variants to the same perceived loudness. It uses the quietest variant as the reference and adjusts all others downward to match. This way no clipping occurs and no limiting is needed.

1. Click Auto Level on a track version.
2. MixReview calculates and fills in the gain values automatically based on the LUFS of each variant.
3. You can still adjust individual values manually afterwards.
4. Click "Reset to album default" to go back to the album-level settings.

Playback shortcuts

• Space bar: Start or pause playback.
• 0: Return the playhead to the beginning.

Adding, replacing or deleting individual variants

• Click the replace icon below a variant button to replace it with a new file. The LUFS value is recalculated automatically after upload.
• Click the trash icon below a variant button to delete it from the mix version.
• To add a missing variant to an existing mix version, click the green empty variant button (e.g. "+ Add Binaural").

What happens when you downgrade

If your current storage usage exceeds the limit of the new plan, a prompt will appear asking you to free up space before the downgrade takes effect. You will need to delete tracks or albums until your usage is within the new limit.
