MPC Audio Splitter 1.8.9.135

Drop a Comment

MPC Audio Splitter fills one very specific gap: it handles the audio splitting and decoding stage inside MPC-BE, processing high-fidelity formats that generic solutions routinely mangle or silently downmix.

If you are getting no sound, lossy output from a lossless file, or dropped audio on DTS-HD and TrueHD tracks, this is the filter you need.

What MPC Audio Splitter Actually Does

A media player does not decode audio in a single step.

When you open a file, a splitter demuxes the container and separates the audio stream, then passes it to a decoder, which converts the encoded data into PCM audio your system can output.

MPC Audio Splitter handles both halves of that process for audio-only and audio-in-video scenarios within MPC-BE.

It registers as a native DirectShow filter, meaning it integrates automatically into MPC-BE's filter graph without manual configuration.

You install it, restart the player, and it takes over audio handling for every supported format immediately.

For a deeper look at how this pipeline works, the How Codecs Work guide covers the full DirectShow chain from container to audio output.

High-Definition and Lossless Format Support

MPC Audio Splitter earns its place specifically because of what it does with demanding audio formats. DTS-HD Master Audio and Dolby TrueHD are passed through as full bitstreams to external DACs and AV receivers, preserving every bit of the original master recording.

Generic codec packs frequently downmix these formats to standard DTS or AC3 without warning.

Beyond the high-definition cinema formats, the filter covers the full range of lossless and specialist audio codecs:

FLAC decoding includes full ID3v2 tag support and HTTP streaming optimization - useful if you stream lossless audio from a local media server.

Monkey's Audio (APE) is handled with complete APE Tag support for detailed metadata preservation.

WavPack DSD support covers hybrid lossy/lossless compression for DSD audio streams from SACD rips.

TTA (True Audio) is supported with real-time lossless compression and ID3v2 metadata. DSF and DFF files - the Direct Stream Digital formats used in audiophile SACD collections - are handled natively.

TAK (Tom's Audio Kompressor), one of the most efficient lossless codecs available, is also fully supported.

For DTS and AC3 standalone file playback, the DTS/AC3 Source Filter remains the dedicated option if you need those formats outside of a container.

For advanced per-channel processing and dynamic range control in surround setups, AC3 Filter covers that use case separately.

Where MPC Audio Splitter Fits in Your DirectShow Setup

MPC Audio Splitter is one component, not a complete solution. It handles the audio leg of your playback chain. You still need a video decoder and, depending on your container format, a dedicated splitter for the video side.

LAV Filters is the standard pairing here - it handles video decoding for HEVC, H.264, AV1, and VP9 with hardware acceleration, and its integrated LAV Splitter handles MP4, MKV, and most other modern containers.

For MKV files specifically, Matroska Splitter is a focused alternative that demuxes MKV and WebM containers with minimal overhead.

For MP4 containers, the dedicated MP4 Splitter handles container parsing cleanly when you want individual components rather than a bundle.

If you need to switch between multiple audio tracks in MKV or MP4 files - original language, dubs, commentary - MPC AudioSwitcher pairs directly with MPC Audio Splitter to give you in-player track control without relaunching the file.

The companion MPC Audio Decoder extends format coverage further if you encounter codecs beyond what the splitter handles alone.

Users who want everything preconfigured without assembling individual filters can take the K-Lite Codec Pack route - it bundles LAV Filters, MPC-HC, and core DirectShow components in one tested installer.

The trade-off is that MPC Audio Splitter's deeper MPC-BE integration and full DSD support are not part of that bundle.

MPC Audio Splitter vs Generic Codec Packs

The practical difference between installing MPC Audio Splitter and reaching for a large codec pack comes down to precision versus coverage.

A codec pack installs dozens of filters and tries to handle every possible format and player combination. MPC Audio Splitter installs one filter that does one job correctly.

Feature	MPC Audio Splitter	Generic codec pack
Download size	777 KB	50 - 150 MB
Installation time	Under 1 minute	2 - 5 minutes
System impact	Single DirectShow filter	Registry bloat, conflicts
MPC-BE integration	Native, automatic	Generic compatibility
DTS-HD / TrueHD output	Full bitstream passthrough	Often downmixed
DSD (DSF / DFF) support	Yes	Rarely included
Update cycle	Active, with MPC-BE releases	Variable, often abandoned

What Changed in Version 1.8.9.135

This release addresses both quality and reliability issues across multiple formats.

DTS-HD processing receives improved bitstream handling for complex surround mixes. FLAC HTTP streaming performance is faster for online playback scenarios. Multiple ARTIST tag support is now preserved correctly for compilation albums.

On the fixes side: WAV files with extended radio broadcast headers are now handled properly. ID3v2.3 album artwork display in media players is restored. APE tag reading is corrected for certain file variations.

An audio dropout issue at the beginning of FLAC files is eliminated. RAM usage for large audio files is reduced, and mixed-format playlist startup time is improved.
