On iPhone/iPad, tap the + button in the Sources tab and select files from the Files app. You can also set up an iCloud folder for automatic syncing. On Mac, go to Settings and choose a library folder — Flacseed will reference files in place without copying them.
Flacseed plays FLAC, ALAC (Apple Lossless), WAV, AIFF, MP3, AAC, and most common audio formats. For bit-perfect playback, we recommend lossless formats like FLAC or ALAC.
When you see "Verified Bit-Perfect" in the fidelity badge, it means Flacseed has exclusive access to your audio output and the sample rate matches your file exactly. Your audio is playing without any resampling or processing by the operating system.
Flacseed uses FFT (Fast Fourier Transform) analysis to detect the actual frequencies present in your audio. When two carriers with a small frequency difference are detected, we calculate and display the beat frequency. This is a measurement of your audio file, not a marketing claim.
Yes. Go to Settings in the app and tap "Restore Purchases." As long as you're signed into the same Apple ID, your purchase will be restored. Flacseed is a universal purchase — one payment covers iPhone, iPad, and Mac.
Flacseed supports Icecast streams in FLAC, Ogg Vorbis, and MP3 format. Make sure your stream URL is correct and the station is online. Some streams may require specific URL formats — try adding or removing the port number, or check for an .m3u playlist file that contains the actual stream URL.
In Studio, open your mix and tap the render/export button. Flacseed will render your layered mix to a new FLAC file that you can add to your library or share.
