New Features

TimeBase now provides a helper to calculate a clock time from a Duration.

GenericAudioBuffer and AudioSlices are now cloneable

GenericAudioBuffer and GenericAudioBufferRef are now sliceable.

Channel information is parsed for Opus tracks in ISO BMFF containers (M4A, MP4, etc.).

Bug Fixes & Improvements

Significantly improved performance of loading media files with large attachments, visuals, or metadata.

Fixed a bug where silent sections were not decoded if certain conditions were met for MP3 files.

Fixed a bug where Xing/Info and VBRI tags were ignored if the MPEG frame containing it had a CRC.

Fixed decoding of mono MP1 audio.

All unwraps have either been replaced with expect or made to return a runtime error.

Hardened demuxers against allocating obscene amounts of memory when reading maliciously crafted files.

Fixed a significant number of panics discovered by fuzzing or AI.

0.6.015 May 2026Breaking

As such there are significant breaking changes present in this release for existing users.

Welcome to Symphonia 0.6! 👋

Symphonia 0.6 is the culmination of two years of effort to rework Symphonia from an audio-focused multimedia framework to one that can be extended to support video and subtitles as well. While Symphonia does not yet support video and subtitle decoders, the groundwork laid in this release should allow easier prototyping of those features, and to more seamlessly introduce them in the future. As such there are significant breaking changes present in this release for existing users.

See the migration guide for detailed information on how to move to Symphonia 0.6.0.

New Features

Format readers and decoders may now be registered with a preference tier/priority
Format and metadata readers now provide methods to get information about themselves
Format readers can now expose attachments (e.g., attached fonts)
Decoders can now decode from non-owning packets, eliminating a copy if using a non-Symphonia demuxer
ID3v1, APEv1, and APEv2 metadata formats are now supported
Added support for chapters for Matroska, ID3v2, and Vorbis Comments
Added support for Matroska metadata
Image format and parameter detection for visuals
Metadata tags that have an official or defacto meaning are parsed where possible (e.g., a track number tag is parsed into an u64)
MediaSourceStream, and all downstream consumers (e.g., FormatReader), are now generic across the lifetime
SIMD optimizations are enabled by default

Bug Fixes & Improvements

Note

This section is not a detailed list of API changes. Please see the migration guide for a detailed listing.

Redesigned all audio primitives
Redesigned most metadata primitives
Redesigned timestamp, time base, and duration types
Format readers now return Ok(None) when the media has ended
Probe now uses a scoring system to better avoid false positives
Metadata encountered while probing for the media format are queued to the format reader
Track-level information not related to the codec (e.g., all timing information) have been moved out of codec parameters and is more reliably populated
Codec parameters are more reliably populated
Rewrote Matroska demuxer to be safer
Rewrote portions of MP4 demuxer to be safer
Improved implementations of AIFF and CAF
Many fixes from panics discovered through fuzzing
Myriad miscellaneous fixes
Decoding performance improvements
Reduced binary size
Improved documentation
Established an official project MSRV policy: Incrementing the MSRV is a breaking change
