FL Studio .wav files that won't import, and why
You drag a sound from FL Studio's folders into REAPER and get "Could not import 1 of 1 items." The file ends in .wav, so it should just work. It isn't really a WAV.
What's inside those files
A WAV file is a container, and most hold plain PCM audio. Image-Line's own knowledge base says many .wav files included with FL Studio are Ogg-encoded: compressed Ogg Vorbis audio inside a WAV wrapper. Others are FLAC files that simply carry a .wav name.
It isn't a handful. When we scanned the content folders of one FL Studio 2024 install by what each file really holds, more than 3,000 .wav files held Ogg Vorbis audio and 139 held FLAC.
FL Studio reads them fine, so you never notice inside FL. Other programs that expect PCM in a WAV can't. REAPER, for one, opens the Ogg ones with a length of 0.000 seconds and refuses to import them.
How to tell which files they are
The file name won't tell you. You have to look at what's inside. In WavSniper, the Type column reads each file's contents and shows these in amber, as Ogg (.wav) or FLAC 16-bit (.wav), next to ordinary files like WAV 24-bit.
Our free Media Codec Scanner shows the real codec of any audio or video file too, and can scan a whole folder.
Three ways to get a WAV your DAW will take
1. Drag it from WavSniper. When you drag an amber file into your DAW, WavSniper hands it a standard WAV copy instead, made once and kept in Documents\WavSniper\Converted. Tested by dropping both kinds into REAPER. Your DAW project points at that copy, so keep the folder.
2. Convert a batch. Select the files and choose Convert to › WAV. FLAC audio keeps its bit depth exactly. Ogg audio becomes a 32-bit float WAV, so nothing clips. Files already in the output folder are skipped, and the originals stay where they are.
3. Use Image-Line's codec route. Image-Line's knowledge base describes installing a Vorbis ACM codec so these files load. That helps programs that use Windows' audio codecs; it doesn't change the files, so a DAW that only reads PCM WAV still won't take them.
One thing no tool can do: an Ogg file was compressed when it was made, and converting it to WAV keeps the sound as it is now. It can't bring back what the compression removed. FLAC is lossless, so its WAV copy is exact.
Questions
Why does REAPER say "Could not import" on an FL Studio .wav file?
Many .wav files that come with FL Studio hold Ogg Vorbis or FLAC audio instead of PCM. FL Studio reads them, but REAPER and other programs that expect PCM in a WAV refuse them. A standard WAV copy imports normally.
Are these FL Studio files damaged?
No. They play correctly in FL Studio. They are compressed audio with a .wav name, which only programs that read that format can open.
Does converting them to WAV lose quality?
FLAC to WAV is exact. Ogg Vorbis was compressed when the file was made; converting keeps the sound as it is now, saved as a 32-bit float WAV, and cannot restore what the compression removed.
