Improvements

• Arabic support

• Bug fixes

Known Issues

• In iOS 11.0, iPhone would not always recognize when an MV88 microphone was connected. If you are experiencing this issue, please upgrade to iOS version 11.1 or higher.
• A small percentage of users may receive a numerical error message while recording, such as “-1” or “66570.” These messages occur when there was an error writing to the device and are related to Apple’s new file system (APFS). One of these errors can occur even if your device has plenty of remaining storage. We recommend clearing up your device storage from the Settings screen, and if that doesn’t resolve the issues, doing a full restore from iTunes, consisting of backing up your device, wiping/restoring to factory settings, and restoring from the backup.
• If you monitor your recordings with Bluetooth earphones, you may hear artifacts, such as noise, while monitoring. If this occurs, we recommend changing the sample rate of your recordings. Some products may produce artifacts at 44.1 kHz, while others may do so for 48 kHz recordings. Please keep in mind that even if you hear artifacts while monitoring, they will not be present in the recordings themselves.
