Spectro for Mac: my fake-lossless checker after seven months of real DJ and audiophile libraries

I posted Spectro here in April ( original thread ). It’s a Mac app that scans a folder and tells you whether each WAV, AIFF, or FLAC is really Lossless a Fake (an MP3 or AAC in disguise), or MEDIUM. I built it because I was tired of opening spectrograms one track at a time and wanted a faster DJ workflow. Fake transcode Then people loaded real libraries.

AI 分析

痛点:DJ 和发烧友需要批量验证下载的 WAV、AIFF、FLAC 是否真的无损,而不是用假 MP3 冒充,逐首查看频谱图太慢。

目标用户:DJ、无损音乐收藏者、数字音乐商店和二手音频交易的验货方

证据:I built it because I was tired of opening spectrograms one track at a time and wanted a faster DJ workflow. / Someone in that thread ran 653 tracks, and that's where the April version fell over. / a bit over 1,000 people have downloaded it since. / for when you need to show a store why a file failed.

变现:Mac 应用一次性买断(约 15–30 美元)加免费试用限制批量数量;Pro 版提供 Rekordbox 集成、Watcher 自动监控、可分享的 Passport 检测报告,面向 DJ 和店铺验货场景。

MVP:两周内做一个 macOS 工具:拖入文件夹后,用 FFmpeg 提取频谱并依据高频截止点批量判定无损、假无损或中等,输出 CSV 或可视化报告,并支持 Rekordbox XML 歌单导入,不做 AI 检测。

竞品:Fakin' The Funk、Spek、Lossless Audio Checker、MusicScope、Tidal/Qobuz 官方校验工具

摘要:作者用七个月重做了 Mac 版假无损检测器 Spectro,支持大曲库批量扫描、Rekordbox XML 导入、文件夹监控和可分享的 Passport 报告,累计下载超过 1000 次,上一版在用户导入 653 首真实曲库时崩溃,暴露了真实需求。帖子没有给出定价或收入数据,付费意愿只能算中等,但 DJ 与发烧友的批量验货需求已被真实使用场景验证。
