Built a browser extension that auto-levels online audio so videos don’t blast my ears.

Hey everyone — I built a browser extension called Compressr that automatically evens out loudness while you watch videos, streams, and podcasts. The problem is painfully common: one minute the dialogue is quiet, the next minute an ad or explosion is suddenly blasting at full volume. I wanted something that makes audio feel consistent without constantly reaching for the volume knob. Compressr works in real time in the browser and keeps the processing local. It’s not uploadi

AI 分析

痛点:在线视频、直播和播客的音量忽大忽小,安静对白与突然的广告/爆炸声落差巨大,用户要不停手动拧音量。

目标用户:长时间在浏览器上看 YouTube/Twitch/播客的用户,尤其是戴耳机、夜间观看或对突发噪音敏感的人。

证据:one minute the dialogue is quiet, the next minute an ad or explosion is suddenly blasting at full volume. I wanted something that makes audio feel consistent without constantly reaching for the volume knob. / The current version is a working prototype, and I’m mainly validating the core UX

变现:浏览器扩展 Freemium:免费版做基础响度均衡,付费(一次性买断 $5–9 或订阅 $1–2/月)解锁自定义预设、每站点规则、EQ/低音增强与多浏览器支持;也可面向无障碍与老年听力场景做打包授权。

MVP:2 周内用 Web Audio API 的 DynamicsCompressorNode/GainNode + MediaElementSource 做 Chrome 扩展:全局开关、压缩强度滑块、突发音量保护阈值、per-site 白名单与前后对比试听,全部本地处理不上传音频。

竞品:Volume Master、Audio Compressor / Audio Equalizer 类 Chrome 扩展、Chrome/YouTube 内置 loudness normalization、Boom 3D、Sound Booster

摘要:作者在 r/SideProject 发布浏览器扩展 Compressr,实时对网页音频做响度均衡和突发音量保护,全部本地处理,目前是可用原型,主要在验证核心 UX 和浏览器/场景优先级。痛点真实且普遍(广告与对白音量落差),但帖子没有出现任何付费意愿表达或收入数据,且同类免费音量控制扩展竞争激烈,付费转化空间有限。独立开发者用 Web Audio API 两周内可复制出 MVP,变现需靠预设、站点规则等差异化增值功能。
