## What is OTO Sound Collector?

Collect sounds. Make them yours. Play.

OTO turns everyday sounds into a hands-on instrument. Record your voice, a clap or a tap on a cup, shape the sound, and play it on a 16-pad sampler.

SOUNDS: CAPTURE AND SHAPE
• Record with your microphone or import audio files.
• Use the waveform, Start and Length controls to choose your playback range.
• Shape sounds with Pitch, Speed, Filter, Reverb, Delay, Distortion and Reverse.
• Apply monophonic pitch correction with key and scale settings.
• Loop previews, rename sounds, and save your edits.

PADS: PLAY YOUR COLLECTION
• A large 4×4 grid of 16 pads.
• Play multiple pads together and retrigger sounds quickly.
• Explore 15 preset kits, including electronic drums, recorded drums, percussion, marimba and kalimba.
• Combine your recordings with preset sounds in Custom Kits.
• Customize pad names, colors and volume.
• Play with a connected hardware keyboard.

START FOR FREE
Record, import, edit and preview sounds, and play the included presets. Each Custom Kit can have one pad assigned to a user-added sound.

UNLOCK PRO ONCE
• Assign your sounds to all 16 pads.
• Record pad performances directly from the internal audio mix.
• Export and share sounds and performances as WAV files.
Pro is a one-time purchase, not a subscription. See the purchase screen for your local price.

Sounds and kits are stored on your device. Microphone recording requires permission. Pitch correction is designed for single-note sources such as voice, not for separating notes in chords.
