An AI sound effect generation service for creators, provided by Casio Computer. Write what you want in Japanese text — something like “the sound of a wooden door creaking open” — and the AI generates ambient sounds, object noises, instrument tones, and other sound effects. Sounds generated on a paid plan are royalty-free and cleared for commercial use, so they can go straight into video, game, and streaming projects. The service was officially released on August 27, 2025, and in March 2026 it expanded into a “sound material platform” that also sells official sound sources from classic Casio electronic keyboards such as the VL-1, SK-1, and MT-40.
Key Features
- Sound effect generation from Japanese text: Even without experience writing English prompts, you can simply describe the sound you want in Japanese. Being able to give instructions in everyday wording — “rain hitting a tin roof” — rather than technical audio terms is the main difference from overseas audio generation services
- Multiple patterns from a single prompt: One instruction returns several candidates, so you can pick the one that fits the scene. Parameters such as fidelity, duration, and the number of generations can be adjusted to get closer to what you had in mind
- Variations built from existing generations: Starting from a sound you like, you can create alternate versions that keep the same character. Useful when a sound repeats across a scene, or when you want distinct variants per character
- Discovery for browsing other users’ sounds: You can search and download sounds published on the service. It often saves you from generating from scratch, and doubles as a reference for how to write prompts
- Official sound sources from retro Casio instruments: Built-in rhythms, tones, and one-shot samples from 1980s classics — the VL-1 (a monophonic synth with a built-in calculator), the SK-1 (with sampling), and the MT-40 (home of the reggae “Sleng Teng” rhythm) — are available as one-time purchases. As manufacturer-official sound sources, they are cleared for commercial use
- Royalty-free commercial use: Sounds generated on a paid plan can be built into videos, games, and apps with no additional licensing fees

Pros & Cons
✅ Pros
- Instructions can be written directly in Japanese, so there is no need to translate or reword prompts
- Paid plans provide royalty-free commercial use, cutting down on license verification work
- The free plan lets you test generation quality before committing to a paid plan
- You can create the niche sounds that stock libraries never seem to carry
- Official Casio retro instrument sound sources are material you cannot get anywhere else
⚠️ Cons
- The free plan is capped at 20 credits a month and blocks commercial use, so professional work effectively requires a paid plan
- Output quality varies with the prompt, and it often takes several attempts to land on the intended sound
- The focus is on sound effects and material sounds; it is not a service for composing full musical tracks
- The interface and prompt collections are Japanese-centric, which can be awkward for collaboration with overseas teams

Where competing generative services assume English prompts, Waves Place is built around writing in Japanese. Compared with stock distribution sites, the difference is the ability to create a sound that simply does not exist in any library.
Who Is It For
- Video editors and game developers who cannot find a sound effect that fits the scene in stock libraries
- Anyone who finds writing English prompts tedious and wants a workflow that stays in Japanese
- Creators on commercial projects who want the licensing of their audio to be unambiguous
- Streamers and podcasters who want to craft their own jingles and sound effects
- Music producers who want to use 1980s Casio keyboard sounds under a proper license
Summary
Waves Place is a Casio-built sound material platform with an easy-to-grasp strength: generating sound effects from Japanese text. The free plan is designed for trials — 20 credits a month, no commercial use — so real production work starts at the ¥980/month Starter plan. If you have ever spent hours searching stock libraries for a sound that was not there, it is worth checking generation quality on the free plan first. With the addition of one-time purchases for retro instrument sound sources, the service now covers both AI-generated and hardware-derived material in one place.
