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 a username for the client, along with first and last name. An email address is optional.
4. Click "+ Add client".
5. Share the access link: click the "Share" button to open the share modal. From there you can copy a ready-made invite message, open a pre-filled draft in your mail client, or send the invitation directly via MixReview (email required).
6. The client opens the link and signs in with their username or email and the personal access code. No account needed.

What clients can and cannot do

Clients can:

• Listen to all mix variants (Stereo, Dolby Atmos (Binaural Downmix), Apple Spatial)
• 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.
• Share: Opens a modal with the access links and additional actions for this client (see below).
• Delete client: Removes the client and invalidates their code permanently.

The Share modal contains the following actions. If you added the client with a username only (no email address), the email-related actions are not available.

• Copy message to clipboard: Copies a ready-to-send invite message (including the access link and code) to your clipboard so you can paste it anywhere.
• 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. Only available if the client has an email address.
• Send invitation: Sends the invite email directly via MixReview. Only available if the client has an email address.
• Keep Client 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. Toggle it off to stop notifications for that client. Only available if the client has an email address.

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 Spatial Prerendered, Apple Spatial JOC) is detected automatically from the filename. The detection is smarter than simple keyword matching — it learns the naming pattern of your files.
• If a file is not recognised, it is flagged in red. Use the variant dropdown on that file to assign it manually.
• You can manually bundle groups before uploading. Drag one bundle onto another to merge them, or use the "Bundle with" buttons.

MixReview includes a custom parser that lets you review and correct how filename tokens are classified. It is a power-user feature — activate it via Customize Parser in the inline help menu (the ? button next to the Batch Upload heading).

Adding new tracks vs. new versions

Batch Upload works the same whether the album already has tracks or is empty. Each bundle either creates a new track or adds a new mix version to an existing one — depending on the filename.

• If the track name in the filename does not match any existing track, a new track is created.
• If the track name matches an existing track, a new mix version is added to that track.

New mix versions always appear at the top of the track card — the most recent version is always shown first.

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.
