2024.10.01

Summary

This update introduces expanded Wi-Fi capabilities, including a significantly longer list of available access points during scans, and adds a convenient link to firmware release notes. Additionally, an important fix addresses automatic monitoring and reset of the Space Recorder’s fuel gauge to ensure reliable operation.

Added

• Wi-Fi list when scanning for access points can now display up to 4 times more results.
• URL linking to firmware release notes is now included for easier access.

Fixed

2024.09.02

Summary

This update includes important bug fixes, specifically refining the firmware update process to preserve and adapt recordings to the new file structure.

Fixed

• Refined firmware update process for versions older than 2023.12.19-2 to ensure all recordings are preserved and adapted to the new file structure.

 

2024.08.13

Summary

New enhancements include automatic volume adjustment for Stellar Mics to prevent distortion during loud recordings, improved synchronization of audio, and more efficient management of old firmware and recordings.

Added

• Delete old firmware updates from disk.
• Delete recordings that should’ve been deleted from disk.
• Enable Automatic Gain Control (AGC) on Stellar Mic. This feature dynamically adjusts gain when recording very loud audio to avoid clipping distortion.
• Improved audio sync.

Fixed

• Resolve an issue where Stellar Mics shut down when undocked after booting up.

 

2024.06.14

Summary

This release introduces advanced storage management features in preparation for upcoming USB file access capabilities, along with new battery management routines and shipping mode enhancements.

Added

• Introduce new storage management capabilities to prepare for USB file access which will be released at a later date.
• Implement new shipping mode and battery charge routines.

Fixed

• Resolve an issue where the Ambisonic encoder did not close after recording.
• Fix the AWS Update Check getting stuck in a reconnect loop.
• Address an issue where abandoned recordings could be deleted from the disk.
• Ensure Stellar Mics are correctly updated even if some are missing.

 

2024.06-04-2

Summary

Key additions include expanded Bluetooth and Wi-Fi support, streamlined microphone replacement processes, and enhanced metadata extraction for audio files.

Added

• Add Bluetooth API version.
• Restart of dock during Space Recorder boot procedure
• Introduce an auto-kitting feature for seamless replacement of Stellar Mics in Sound Capsule kits.
• Enable Wi-Fi Enterprise Support for connecting Sound Capsule to enterprise Wi-Fi endpoints.
• Add an ability to view device serial numbers and MAC addresses in the "My Devices" view within our control panel.
• Enable metadata extraction for all audio files, allowing Cloud to retrieve detailed recording information.

Fixed

• Ensure correct response to Wi-Fi-scan requests.
• Fix a "ghost recording" issue which led to an incorrect number of recordings being displayed in the upload queue.
• Enable recording while in Flight Mode.
• Ensure resuming of Cloud upload after Flight Mode recording.
• Improve Stellar Mic charging in factory mode.
• Resolve the recording timer inaccuracy issue when Space Recorder receives an NTP update during recording.
• Improve the Charging Case to prevent it from charging Stellar Mics and Space Recorder when the battery is low, ensuring safer and more reliable charging.
• Implement a delay for Sound Capsule upgrades until file uploads are complete to prevent potential disruptions.
• Prevent the Stellar Mic from entering and exiting shipping mode while charging if the battery is below 2%.
• Fix an issue where recordings created on older firmware versions are stuck in the upload queue due to a discrepancy between the older recording name and the new naming convention introduced in version 2024.02.22. This update ensures that a new formatted name is generated for recordings lacking one, thereby facilitating successful uploads to the Cloud. If a recording was made with version 2023.12.19-4 or older and the Sound Capsule was upgraded before the recording was uploaded to Cloud, the result would be a frozen upload queue.

 

2023.12-19-4

Summary

This update addresses critical issues to ensure the stable operation of Stellar Mics during recordings.

Fixed

• Fix an issue where Stellar Mic could crash in the middle of a recording

2023.12-19-2

Summary

Significant improvements include the ability to initiate firmware updates via Bluetooth, new control panel features, flight mode and substantially faster data transfers post-recording.

Added

• Add the possibility of starting a firmware update via Companion (bluetooth)
• Add Flight Mode (Disables charging and Wi-Fi connectivity)
• Add Control Panel in Space Recorder GUI. For now, it is possible to select "Reboot", "Flight mode" or "Check for updates". To go into the control panel, press and hold the down button on the Space Recorder for 5 seconds.
• Display final recording time while fetching data from stellar mics after recording
• Show warning LED during recording if a stellar mic buffer is almost full
• Add warnings related to stellar mic buffer fill, slow data transfer and out-of-range
• Add a warning when trying to reboot during firmware upgrade and/or recording
• Automatically stop recording when all devices are docked for more than 60 seconds

Changed

• Improve encoder speed, leading to faster response and lower battery usage
• Change how trim/extend of Stellar Mic WAV-files are done
• Faster and better stellar mic sync
• Optimize transfer speed of audio data from Stellar Mics to Space Recorder during and after recording. This means significantly less waiting for data transfer after a recording has been stopped. In our own tests, the data transfer time after a long recording with all four stellar mics could be reduced from up to ~20 minutes to only ~2 seconds!

Fixed

• Fix header margin in low local storage warning
• Improve recording timer accuracy
• Fix an issue where a Stellar Mic could sometimes get stuck in a loop after recording
• Fix an issue where uploaded recordings were not correctly deleted
• Automatically reboot charging case if it reports dropped messages
