Version 5.27.1

Release overview

The 5.27.1 release contains various bug fixes and improvements. For further technical details on all the changes included in this release, refer to the 
CHANGELOG.md
file within the SDK.

Key features and bugs addressed

Added
  • Vivox clients now reconnect automatically when Vivox servers make live upgrades.
Changed
  • Windows: Only audio input devices now have the 
    AudioCategory_GameChat
    AudioCategory specified by default due to Windows forcing some Bluetooth devices into a low quality mode when 
    AudioCategory_GameChat
    was specified for an audio output device. Use 
    vx_sdk_config_t.capture_audio_stream_category
    to change the capture audio stream category at initialization.
Fixed
  • Android: Building the SDKSampleApp from source is now achievable in modern Android Studio versions without major build file changes.

Version 5.27.0

Release overview

Version 5.27.0 introduces support for the Nintendo Switch™ 2 and fixes bugs related to Android and Automatic Connection Recovery (ACR). For further technical details on all the changes included in this release, refer to the

file within the SDK.

Key features and bugs addressed

  • Android armeabi/armeabi-v7a: Fixed a crash that would occur on certain SoCs at the time of Vivox login when custom allocators were not specified.
  • Fixed layered service provider debug log spam from Automatic Connection Recovery (ACR).
  • All time-dependent operations within the Vivox SDK are now immune to system clock changes.
Windows

Version 5.26.0

Release overview

Version 5.26.0 introduces comprehensive audio processing improvements with enhanced noise suppression, expanded platform support for audio processing features, and significant performance optimizations. This release focuses on improving voice quality while optimizing resource usage across all supported platforms. For further technical details on all the changes included in this release, refer to the 
CHANGELOG.md
file within the SDK.

Key Features and Bugs Addressed

  • Updated license and third-party notices.
  • Vivox log levels were off-by-one. There may be more Vivox log statements now if initial_log_level was set for your application.

Audio Processing Improvements

  • Noise suppression now applied to capture audio by default.
  • Extended Acoustic Echo Cancellation (AEC) and Automatic Gain Control (AGC) support to Nintendo Switch™, PlayStation®, Xbox, visionOS, and UWP.
  • New AEC implementation prevents microphone dropouts in the presence of echo on mobile platforms.
  • AGC enabled by default with improved microphone capture loudness.
  • Optimized voice codec for reduced packet loss and jitter.

Performance Optimizations

  • Existing AEC/AGC platforms:
    • 11 MB reduction in memory usage during active sessions.
    • Improved CPU efficiency in Release configuration.
  • New AEC/AGC platforms:
    • 44% increase in audio thread CPU usage.
    • 6 MB additional memory usage during sessions.
  • Memory allocator improvements reducing heap memory requests.

Platform-Specific Changes

  • Android: Added 16KB page size support for native libraries
  • Android: Proguard rules now included in AAR libraries
  • iOS: Removed support for ARMV7 architecture
  • iOS: Removed bitcode
  • Android/iOS: Improved platform AEC control independent of DVPS

Implementation Considerations

  • Consider adjusting application volume presets due to new AGC behavior.

Public API Changes

New APIs

  • vx_get_noise_suppression_enabled
  • vx_get_noise_suppression_level
  • vx_set_noise_suppression_enabled
  • vx_set_noise_suppression_level
  • on_audio_unit_requesting_final_mix_for_echo_canceller_analysis

Modified APIs

  • vx_set_platform_aec_enabled
    - Now functions independently of Dynamic Voice Processing Switching (DVPS) status.

New Error Code

  • Added 
    VxXmppErrorChannelAtCapacity (20507)

Known Issues

  • Android sample applications do not yet support 16KB page size despite native library support.
