YOUR TRACKS. YOUR TRANSITIONS.Record above to save your live mix.

Getting started & supported audio

Load a file into each deck, choose saved takes, or play Neon Meridian, an original 32-bar arrangement split across two decks.
Press Play. Turn the jog wheel to scrub forward or backward, or adjust the seek slider. Set hot cues at favorite moments, then tap them to jump and play.
Review the detected BPM in Beat grid, or tap it in. Check the first downbeat. Enable Quantize to launch hot cues and beat loops on the next beat, then blend with the crossfader.
Shape the mix with EQ, filters, and echo. Set In and Out for a loop, or choose its length in beats.
Press Record above to capture the live mix. Open Recordings to listen and export WAV. Add decks to the tune editor to arrange the original sources.

Jog wheel keyboard: arrow keys move 0.1 seconds; Shift + arrow moves one second. Home and End go to the start and end. Escape pauses both decks. Mixer knobs: drag left or right, or focus a control and use the arrow keys. On a phone, choose Deck A or B above the mixer.

WAV, MP3, AAC/M4A, FLAC, Ogg/Opus, AIFF, ALAC, WMA, AMR, APE, and other unprotected audio formats use native decoding with an on-device conversion fallback. The extended decoder downloads about 31 MB on first use and needs an internet connection. Files stay on your device. Up to 25 MB and 10 minutes per import; each deck holds up to 96 MB of decoded audio. Some proprietary or damaged files cannot be opened.

Turn on Key lock to preserve musical pitch when changing tempo. Preparation runs locally for mono/stereo tracks up to 3 minutes / 64 MB decoded. Without Key lock, pitch follows speed. Review automatic BPM estimates or enter/tap a grid. Separate headphone monitoring is not included. Audio, cues, grids and mixer settings save on this device. Both decks reopen paused at the last saved position. Decoder credits and source. Pitch processing credits and source.

Voice 80%Backing 70%Recorded voice timing (ms)Voice sounds late? Try a negative value. Positive values place it later. This corrects the recording, not the lyrics or live monitoring. Start with a short test take.

Measure microphone timing

Use speakers at a comfortable level, with the microphone nearby. Five short clicks measure this output-and-input path. Do not wear headphones for this test. No microphone sample is kept.

Room echoes and device processing can affect the estimate. Manual timing remains available. Changing to headphones or another device changes the measured path.

Hear my voice in headphones

Use headphones for monitoring. Bluetooth and browser audio can add a delay. Monitoring is off by default.

How do I sing and record karaoke?

Choose a backing track or try the original demo. Adjust Backing key up to six semitones in either direction to find your vocal range. Paste lyrics or import a plain-text or LRC lyric file, then open Full-screen lyrics for a focused singing view. Your backing, lyrics and settings save on this device. Press Enable microphone when you are ready to sing, adjust the music and vocal levels, then record your performance. Finished takes save in Recordings when browser storage is available. Review and download a copy to keep, or send the performance to Tune Editor without replacing the existing arrangement.

How are the microphone and backing track handled?

Backing tracks and microphone audio are mixed on your device. Microphone access starts only when you enable it, and the microphone is released when you leave karaoke. Monitoring is off initially; use headphones if you enable it. Vocal timing correction shifts voice against backing in the recording by up to 500 milliseconds in either direction; lyric timing is a separate control. An optional speaker-click timing check measures the combined playback and microphone path and lets you review a suggested recording correction before applying it. Backing key adjusts the accompaniment by up to six semitones while preserving its duration and lyric timing. It prepares the track locally before playback and leaves microphone audio unchanged. Key adjustment supports mono or stereo tracks up to three minutes and 64 MiB of decoded audio; larger tracks remain available in their original key. Extreme shifts can sound processed. It does not remove vocals, supply commercial songs or automatically transcribe lyrics.

A few useful notes

Can I change a backing track to fit my vocal range?

Use Backing key to transpose the accompaniment up to six semitones up or down. Its duration and lyric timestamps stay the same, and the microphone is not shifted. Wait for preparation to finish before playing. Processing supports mono/stereo tracks up to three minutes and 64 MiB decoded audio; larger tracks can play in their original key.

Does Resonant include a karaoke song catalogue or remove vocals?

The first version accepts your own backing track and includes an original Resonant demo. It does not include a commercial song catalogue or automatic vocal removal. You can paste your own lyrics or timed LRC lyrics.

Why is microphone monitoring off when I start?

Monitoring plays your microphone through the speakers or headphones. It starts off to prevent feedback. You can record without hearing your microphone live. If you enable monitoring, use headphones; device and Bluetooth latency can affect the timing you hear.
