Holtz Portal

Holtz Portal keeps your Holtz Sound Studio projects close at hand. Listen to audio shared with your account, compare available versions, languages and formats, and leave feedback for the studio. Save selected audio or all available project player sources for offline listening when your account permits downloads. Explore shared stems with synchronized playback, levels, mute and solo. Request a full-quality mix from the studio renderer and download completed results when available. See upcoming and past sessions, exchange studio messages, send and receive project files, and view your available quotes and invoices. Optional notifications let you know about new studio activity. Protect access to the app with an optional Face ID or device-passcode lock in Settings. Holtz Portal is for existing Holtz Sound Studio clients and authorised project collaborators. Sign in with the account provided by the studio. Project access and available actions follow the permissions assigned to your account.
