Go to Settings > Decoder and ensure that "Use speedup tricks" is turned on, or reduce the video playback speed slightly to allow older CPUs to keep up with heavy EAC3 processing.
E-AC3, which stands for (or Dolby Digital Plus), is a digital audio compression format developed by Dolby Laboratories. It serves as an upgraded version of the older AC-3 (Dolby Digital) format, offering several key advantages that contribute to superior audio fidelity. mx player custom codec eac3 extra quality
If you are unsure about your device's architecture or frequently switch between devices, you can download the AIO (All-In-One) pack. This larger file contains codecs for multiple architectures. When you select it under "Custom codec," MX Player will automatically extract and use the correct one for your device. This is a great way to avoid compatibility problems and ensure you have the best possible audio support.
Tap the (three lines or dots) and go to Settings . Navigate to Decoder and scroll to the very bottom.
Compared to its predecessor, E-AC3 supports significantly higher bitrates, enabling more detailed and dynamic sound reproduction. It also features improved compression algorithms, which means it can deliver the same—or even better—audio quality while using less data than older AC-3 codecs. Modern streaming giants like Netflix, Disney+, and Amazon Prime Video rely on E-AC3 to deliver high-quality Dolby Digital Plus and Dolby Atmos soundtracks. Tips for Extra Quality Go to Settings >
As the custom codec began to take shape, the team's excitement grew. They dubbed their creation "eXtended Audio Codec" (XAC). With XAC, they aimed to not only match but surpass the quality of native eAC3 playback. The improvement would be noticeable, especially in the nuances of audio reproduction – the subtle ambiance, the detailed instrumentals, and the crisp dialogue.
In most cases, MX Player will automatically detect the new codec file the next time you open the app. If a pop-up appears asking to use the file, click . If it does not detect it automatically, install it manually: Open MX Player and navigate back to Settings > Decoder . Tap on Custom codec .

The challenge for a media player like MX Player is that E‑AC‑3 decoding requires either a licensed decoder (expensive) or an open-source implementation (e.g., FFmpeg’s libavcodec ) that may be legally restricted in some regions. Custom codecs bridge this gap by allowing users to supply their own FFmpeg builds.
Standard custom codecs may downmix multichannel E‑AC‑3 to stereo or truncate bit depth to reduce CPU load. An “extra quality” build preserves the original channel mapping (e.g., 5.1 or 7.1) and decodes at full floating‑point precision, avoiding clipping or quantization noise.
It is highly recommended to download the AIO ZIP package . This single file contains all architectures (ARMv7, ARMv8, x86) and automatically selects the correct one for your system.
