FLAC Cutter FAQ
How does FLAC Cutter cut the file?
+
Concretely, the cut is sample-exact, so you can place the boundary precisely where you want it rather than on the nearest frame, and the surviving audio is bit-identical to the source. You set the start and end points on the waveform or the timeline and keep what is between them.
How precisely can I place the start and end points?
+
You can type exact timecodes rather than only dragging, and the preview scrubs to the position as you move it. How exact the result can be depends on the format: some allow a cut anywhere, others snap to the nearest frame or keyframe.
Does the format limit where I can cut?
+
It does. FLAC is lossless compression — bit-identical to the source on decode, at about half the size of WAV. That is precisely what decides whether a cut can be placed arbitrarily or has to land on a structural boundary.
Anything specific to FLAC when trimming?
+
Yes — FLAC decodes bit-identically to the source, so any number of edit-and-resave cycles cost you nothing in fidelity. It explains most of the "the cut is a fraction of a second off" surprises.
Can I remove a section from the middle instead of keeping one?
+
Yes — cut the piece before it and the piece after it, then merge the two results. That is deliberately two steps because it keeps both halves on the fast, lossless path instead of forcing a full re-encode.
Is the part I keep re-encoded?
+
Not if the format allows a stream copy — the data you keep is bit-identical to the source and the job finishes in about the time the upload took. Only a frame-exact cut on a format that cannot do it cheaply needs a re-encode.
What can I upload to FLAC Cutter?
+
WAV, FLAC and AIFF, at any bit depth and sample rate up to and including 24-bit/192 kHz. Lossy files work in the same batch if you are mixing sources.
Is there a file size limit on FLAC Cutter?
+
Yes: free accounts process audio up to 200 MB per file — for uncompressed PCM that is roughly twenty minutes of CD-quality stereo, so it is a real limit here in a way it is not for MP3. If you are over it, converting WAV to FLAC first is the free fix — it is lossless and roughly halves the size.
Will FLAC Cutter lower the quality of my FLAC audio files?
+
No. Lossless audio is edited sample-exactly, so what comes back decodes bit-identically to what you would get doing the same edit in a desktop editor. You can repeat the cycle as many times as you like without accumulating any loss at all.
Can I run FLAC Cutter on several FLAC audio files at once?
+
Yes, though lossless files are large, so the batch is bound by upload bandwidth rather than by processing. Settings apply uniformly across the set.
Are bit depth and sample rate preserved?
+
Yes, unless you change them deliberately. A 24-bit/96 kHz source stays 24-bit/96 kHz — nothing is silently downsampled to 16/44.1, which is the failure mode that makes a master unusable.
Does FLAC Cutter cost anything?
+
No. FLAC Cutter is free with no account required, and nothing is added to the audio. Uploads are deleted from the workers shortly after the job finishes.
