Pika SFX
Pika SFX is a sound-effects generation model that turns natural-language direction into focused, ready-to-use audio for video, games, editing workflows, and creative tools. Users simply describe the sound they want, whether it is a glass shattering, a metal door slamming in an empty warehouse, a cork popping and fizzing into a glass, or something more stylized. The model can handle both a single crisp event and longer sequences, with control over material, space, perspective, timing, texture, and mood. It can generate natural Foley, cartoon-style effects, designed fantasy sounds, environmental ambience, and other prompt-driven audio while following the brief closely. Unless requested, it avoids adding unrelated speech, music, or background noise, helping creators generate clean effects that can be dropped directly into a project.

Pika Soundtrack
Pika Soundtrack is a video-to-audio model that turns silent video into a native soundtrack complete with motion-aware sound effects, music, ambience, and voiceover that follow what happens on screen. Users can leave the prompt blank to generate a full soundscape automatically or provide direction specifying what the model should emphasize, include, or leave out. Rather than simply generating sound with video attached, the model is designed to understand what is happening in a scene, place each sound at the right moment, and keep every audio layer coherent throughout the full video. This synchronization approach allows sound effects, ambience, music, and speech to feel as though they belong naturally within the same scene. Pika reports that, in its full-duration benchmark, Soundtrack achieved the strongest semantic alignment and lowest audiovisual desynchronization among the models tested, including LTX-2.3 Foley V2A, HunyuanVideo-Foley, and MMAudio v2.

Mirelo SFX
Mirelo SFX is an AI-powered video-to-sound effects solution that brings videos to life with synchronized, realistic audio. Users can generate sound effects, Foley, and ambience that match their footage while preserving dialogue, removing unwanted audio, and keeping sound consistent across cuts. Instead of searching for, trimming, and syncing individual effects, users can upload a video and automatically generate footsteps, impacts, environmental sounds, and other audio elements that land exactly where they should. The model reads visible action, timing, and environment to synchronize sounds with on-screen events. Its speech preservation technology separates dialogue from the original clip and retains it while generating new effects and ambience, allowing users to remove unwanted background music without losing speech. For multi-clip projects, it maintains consistent audio across transitions, making stitched edits sound like one continuous scene.
