Convert WAV to RX2

A sampler, DAW, or hardware device may require a REX2 loop instead of a standard WAV when it needs embedded slice markers for rearrangement or tempo matching. Converting the file creates an .rx2 file that compatible software can trigger slice by slice.

What the WAV format is

WAV is a RIFF audio container commonly used for uncompressed PCM recordings, DAW exports, sound-design sources, and samples. It is supported by applications such as Audacity, Adobe Audition, Ableton Live, Logic Pro, and Reaper. WAV preserves PCM audio without lossy compression, but a normal WAV does not contain the musical slice structure required by REX2.

What the RX2 format is

RX2 is the file extension for the newer REX2 loop format created by Propellerhead ReCycle, now associated with Reason Studios. It stores loop audio with slice markers and timing information. A compatible sampler or DAW can use those markers to trigger individual hits, rearrange sections, and adapt a rhythmic loop to a project tempo.

REX2 is intended for drum loops, rhythmic phrases, and other material that benefits from slicing. It is not a general replacement for WAV: many media players, audio editors, and DAWs cannot open or export it, and some applications import the audio while ignoring its slice metadata.

How to convert WAV to RX2

ReCycle is the appropriate desktop application because it was designed to analyze audio and create REX or REX2 files. DAWs such as Logic Pro or Cubase may import REX files, but their presence does not mean they can export a valid RX2 file.

1. Open ReCycle and choose File → Open, then select the WAV file.
2. Check the detected tempo and correct it if necessary. Set the loop length, bars, and beats so ReCycle interprets the source at the intended musical length.
3. Adjust the sensitivity and transient detection controls. Move, delete, or add slice markers so they fall on meaningful drum hits or musical divisions rather than inside sustained sounds.
4. Audition the loop at its original tempo and at a different tempo. Remove false slices and adjust boundaries that produce clicks, chopped tails, or unnatural timing.
5. Use the version-specific REX export or save command, normally under File → Save As, choose REX2 (*.rx2), and save the file.
6. Import the resulting .rx2 into the target sampler, DAW, or hardware device and confirm that both the audio and slice markers are recognized.

There is no dependable generic WAV-to-RX2 conversion through ordinary online file converters because creating a useful REX2 file requires slice analysis and marker editing. CloudConvert, Zamzar, or another reputable service should be used only if its current format list explicitly offers RX2 as an output; a service that lists WAV conversion alone cannot create this format. Do not upload confidential or unreleased recordings to an online service when ReCycle can process them locally.

Quality and compatibility limits

Keep the original WAV as the master. RX2 conversion does not improve the source audio, and the exported file can differ in size according to its encoding and slice structure. Retain the original sample rate and bit-depth source for archiving rather than treating .rx2 as the only copy.

Slice placement affects playback more than the file conversion itself. A boundary in the middle of a waveform can cause a click; an excessively long slice can prevent a loop from following tempo changes cleanly. Move boundaries toward suitable zero crossings or use short fades when the material permits.

Support is application-specific. Some hosts support only REX or REX2 import, some support REX2 but ignore embedded tempo or markers, and some hardware imposes limits on sample rate, channels, loop length, or slice count. Test the exported file in the exact software or device that will play it.
