大多数笔记本电脑的扬声器声音单薄空洞,但这通常是由于缺乏软件层面的调音,而非硬件素质欠佳。像 MacBook 这样的高端笔记本之所以音质更好,主要原因在于厂商内置了出厂调校的音频处理方案。 Linux 用户可以使用 **EasyEffects** 来弥补这一差距。这是一款强大的音频处理应用,它利用 PipeWire 来应用均衡器、压缩器及其他音频增强功能。虽然手动调音需要专业知识,但用户可以轻松导入通用的预设(如“Advanced Auto Gain”),从而立即获得显著的音质提升。 该应用的安装过程简单直接,且非常轻量,对 CPU 性能的影响微乎其微。鉴于其卓越的效果,作者认为 Linux 发行版、硬件厂商以及 GNOME 和 KDE 等桌面环境,应当优先考虑将这些音频调优功能设为默认配置。与其忍受平庸的音质,用户完全可以利用现有的 Linux 技术,大幅提升笔记本的听觉体验。

最近的 Hacker News 讨论指出,**EasyEffects** 是改善 Linux 笔记本电脑扬声器糟糕音质的必备工具。用户们提到,正如高端硬件(如 MacBook 或 Sonos)一样,基于软件的数字信号处理(DSP)可以通过应用均衡器和房间校准,极大地弥补小型驱动单元在物理性能上的不足。 **核心要点:** * **性能:** 用户反馈音质有“天壤之别”的提升,特别是对于像 Framework 这样出厂声音“干瘪”的笔记本电脑。 * **预设:** 许多用户通过下载社区创建的预设(例如来自 GitHub)而非手动调试复杂的音频滤波器,就能获得极佳的效果。 * **校准:** 虽然有些人主张使用校准测量麦克风和 Room EQ Wizard (REW) 等工具来创建自定义配置文件,但其他人指出,对于日常使用,简单地提升低频和高频就能带来显著的音质升级。 * **集成:** 社区强烈希望桌面环境(GNOME/KDE)能原生集成此类工具。一些用户还建议从 Windows 驱动程序中提取专有的杜比全景声(Dolby Atmos)配置文件,以在 Linux 上实现录音室级别的调音效果。 总的来说,尽管音频偏好因人而异,但许多人认同“中性”或“平直”的声音是高质量音频回放的专业标准。

Virtually all laptop speakers suck. It’s the one area where even really expensive laptops tend to fall on their ass, leaving users with a tinny, harsh, and hollow sound experience. While you can’t exactly overcome physics – laptop speakers are necessarily small and thus just cannot ever sound as good as proper speakers – there’s a lot you can do with proper tuning and software magic. If you’re a desktop Linux user, you actually already possess all the plumbing needed to fix your audio; it’s just not exposed to you in any way. Luckily, an application called EasyEffects allows you to actually make use of desktop Linux’ advanced audio features to massively improve the sound quality of your laptop’s speakers.

EasyEffects’ own description on its GitHub page doesn’t really explain what it does or what it’s capable of, so here’s the description from Wikipedia instead.

EasyEffects uses PipeWire to process incoming and outgoing audio streams independently and can apply various sound effects in the form of plug-ins made by different developer teams such as Calf Studio Gear, MDA.LV2 and GStreamer. All plugins have their own presets and can be applicable inside the suite rather than having to use a different mixer or executing a script from the command line.

Available output effects are limiter, auto volume, compressor of dynamic range, filter, 30 bands parametric equalizer, bass enhancer, exciter, reverbation, crossfeed, delay, maximizer and spectrum analyzer. Available input effects are WebRTC, limiter, compressor, filter, equalizer, de-esser, reverbation, pitch shift and spectrum analyzer.

None of this matters, and you can forget everything from these two paragraphs.

What matters is that using EasyEffects, you can tune the audio coming out of your speakers to make them sound a lot better. The few laptops on the market that do have decent audio – MacBooks, some Dell XPS laptops, and surely a few more – aren’t magically defying physics. While they probably do have objectively higher-quality speakers, the main difference between those laptops and laptops with crappy-sounding speakers is that the former come with built-in tuning from the factory to make them sound much better than they would without any software trickery.

If you know your way around audio, you can very much use EasyEffects and tune your laptop speakers from scratch to massively improve how they sound. However, that requires time, experience, knowledge, and expertise that most people lack, including myself. Lucky for us, though, there are countless downloadable presets out there for EasyEffects designed specifically to make laptops sound better.

In an ideal world, you’d pick a preset created specifically for your laptop make and model, but odds are you won’t find one, so for most laptops you’ll have to settle for a generic preset that tries to do its best. I’ve long settled on the Advanced Auto Gain.json preset from JackHack96, which greatly improves the audio performance on any laptops I’ve tried it on, but of course, there’s countless other presets for you to try to see if there’s anything that suits your particular laptop and ears better.

Getting all of this up and running is really easy. EasyEffects is most likely packaged by your Linux distribution, and the latest version is always available as a Flatpak from Flathub. Download the preset(s) you want to try, copy them either to ~/.config/easyeffects (if you use your distribution’s package) or to ~/.var/app/com.github.wwmm.easyeffects/data/easyeffects/output/ (if you use the Flatpak version). They’ll show up right away in the Presets tab in EasyEffects, ready to be turned on and off whenever you want, making it very easy to compare and contrast to find the one you like best. EasyEffects can live in your system tray giving you easy access to your presets without having to open the main window, and it can be set to start automatically at boot. EasyEffects can also be turned on and off on the fly.

There’s obvious downsides to all of this, too, of course. First, since you’re most likely going to be using a generic preset not specifically crafted for your laptop, there’s no guarantee the results will be positive for you. Second, not every preset is ideal for every type of audio. Most of my audio consists of YouTube videos with mostly speech; if you listen mostly to music, different presets may yield better results. Third, audio quality is deeply subjective, and what sounds good to my ears may sound like total garbage to yours. Fourth, EasyEffects does take up a tiny fraction of CPU power (I’m talking 0.1-0.2% according to KDE’s System Monitor), but I have never seen it have any noticeable performance impact on anything.

Even the generic preset I use makes such a massive difference for me on every laptop I’ve ever tried it on, that I’ve become convinced EasyEffects and a few of the generic presets should be installed by default by any desktop-oriented Linux distribution. On top of that, Linux laptops OEMs like System76, Nova Custom, Star Labs, and so on, should really take the time to create proper presets for their laptops to improve their sound quality out of the box. I feel like if you’re already designing and selling laptops, you probably also have the skills and means to create a decent preset.

In fact, I’d take it a step further and urge desktop environments like KDE and GNOME to properly integrate EasyEffects into their sound settings. They shouldn’t include the entire application and its user interface, but should make it so that you can configure and manage presets right from the sound settings panels, and switch between presets from their volume applets (as well as turn it off entirely, of course). This would leave the full EasyEffects application for people who need more control, manual tuning, and more advanced features.

There’s absolutely no reason why speakers on Linux laptops should sound tinny, harsh, and hollow. The Linux desktop has all the technologies and features built right in to make speakers sound much better than they do without any tuning, and yet, very few people seem to actually be aware of this. This needs to change, and I think it’s up to distributions, desktop environments, and Linux OEMs to make this happen.
