This blog post details how to improve the GPD Pocket 4's weak built-in speakers by configuring PipeWire's DSP (Digital Signal Processing). The author uses pw-cli commands to implement a simple equalizer with bass boost and gain adjustments, demonstrating how to create and load a custom configuration file. This process enhances the audio quality significantly, making the speakers more usable for casual listening. The post also explains how to automate the configuration loading at startup using a systemd service, ensuring the improved sound profile is always active.
This blog post details a process for enhancing the audio output quality of the GPD Pocket 4, a mini-laptop known for its compact size, by configuring its Digital Signal Processor (DSP) through the PipeWire sound server. The author identifies the Pocket 4's speakers as a weak point, describing the default sound as "tinny" and lacking bass. Instead of resorting to external speakers or headphones, they explore a software-based solution using PipeWire, a modern, low-latency audio and video processing system.
The core issue lies in the factory DSP configuration, which seemingly prioritizes loudness over sound quality. The blog post walks readers through installing easyeffects, a graphical user interface for PipeWire that allows for easy manipulation of audio effects. Crucially, the author provides specific configuration settings, including an equalizer curve and compressor settings, tailored to the GPD Pocket 4's speakers. These settings aim to boost the bass frequencies, reduce the harshness of higher frequencies, and improve the overall dynamic range.
The author meticulously describes the installation process of easyeffects and emphasizes the importance of selecting the correct audio output device within the application, a step that can be easily missed. They further explain how to apply the provided equalizer and compressor configurations, recommending saving these settings as a preset for convenient future access. The blog post even provides a detailed explanation of how to automatically load this preset upon startup, ensuring the improved sound profile is consistently applied. This automation involves creating a dedicated script and adding it to the system's startup applications, demonstrating a thorough approach to implementing a persistent solution. Finally, the author shares their subjective experience with the improved sound, reporting a significantly richer and more balanced audio output after applying these adjustments. They conclude by acknowledging that the improvements are subjective and dependent on individual preferences, encouraging readers to experiment with the settings to achieve their desired sound profile.
