Noise Eraser vs Google Flow Music (formerly Riffusion)

Noise Eraser pulls apart vocals, wind, traffic, music, and air conditioning noise so you can keep the sounds you want and drop the rest. Upload an audio or video file, pick a separation target, and fine-tune the mix with sliders. DeepWave offers it as a browser studio and a mobile app for creators who need cleaner speech without rebuilding the track in a full DAW.

Most denoisers apply one blanket filter across the whole clip. Noise Eraser splits individual sound types so you can keep the voice while dropping wind, or mute traffic without touching the music bed. The free tier handles vocal separation only; paid plans unlock up to five separation models with stereo output on Pro+.

Podcasters, vloggers, and social media editors use it to salvage clips recorded outdoors, in cars, or near HVAC units. The mobile app supports full video files end to end, which matters when you are fixing audio straight from a phone recording rather than exporting stems first.

Google Flow Music lets you create full-length songs, remix tracks, and publish music through a conversational studio built on Google's Lyria 3.5 model. riffusion.com now redirects to flowmusic.app, where you chat with Producer like you are in a session, iterate on vocals and arrangement, and export finished tracks.

Unlike one-shot music generators that spit out a clip and stop, Flow Music focuses on iterative editing. Replace and Extend let you swap specific sections or continue a song past its endpoint without regenerating the whole track. You can also direct Veo-powered music videos, split stems, apply audio effects, and vibe-code custom instruments or mini apps inside Spaces.

The free tier includes daily top-up credits and two concurrent generations with no credit card required. Paid plans raise monthly credits, concurrent generation limits, and add member perks. Google acquired the Riffusion team in 2026 and folded the product into Google Labs alongside Lyria and Veo.
