MP3 to WAV — 常見問題
Why is the WAV so much bigger?+
WAV is uncompressed PCM — roughly 10× an MP3. That's expected: it's the trade-off for a lossless, editing-friendly file.
Does converting to WAV improve quality?+
No. It can't restore detail the MP3 already discarded — but it won't lose any more, which is useful before further editing.
Is it uploaded?+
No — the MP3 is decoded and the WAV is written entirely in your browser.
What sample rate is the WAV?+
The same sample rate as the source MP3, as 16-bit PCM.
你們會把我的檔案上傳到伺服器嗎？+
不會——這裡的每個工具都完全在你的裝置上處理檔案，不會向伺服器上傳任何內容。唯一的例外是 AI 工具，它們會把擷取的文字（而非檔案本身）傳送給 Claude 來完成工作。
有檔案大小限制嗎？+
我們沒有人為設下限制，但由於處理過程在你的瀏覽器中進行，非常大的檔案（超過 500MB 或 1000 頁）會受你裝置記憶體的限制，而非我們的限制。
