Muzaic.ai is a browser-based tool that scores video automatically. You give it a cut (or a folder of cuts); it returns a finished audio mix — music, SFX, ambience and voiceover as separate layers — mastered to broadcast spec, in roughly 30 seconds per clip.
What it actually does
The pipeline runs in four stages. First it analyses the video: scenes, objects, pacing, colour and sentiment. From that it builds an audio plan and commits each concept to a clear direction (the site's example: a string quartet under a battle scene) rather than averaging toward something inoffensive. Then it composes every layer to fit the picture and the other layers — SFX land on the action, ambience ducks under speech, the voiceover is drafted from your brief rather than read out. Finally it mixes and masters the result. Existing audio in the source can be kept, replaced or mixed under.
Output is three concepts per clip, exported as MP3 or WAV. Layer balance is adjusted inside Muzaic before export; the deliverable is the finished mix, not separate stems.
The commercial angle
Pricing is metered in minutes of finished audio, not per track or per download; downloads are unlimited. Personal is free for 10 minutes a month, non-commercial only. Creator ($45/month) covers your own brand and paid ads. Studio ($249/month) is for agencies: the licence travels to the client and the legal cover extends to them too. Enterprise adds TV, radio, cinema and OOH, plus a custom contract, DPA and SLA.
What it is not
It is not a music-generation toy. The free tier exists to test the workflow on your own footage; nothing from it may be published. The target user is a team producing hundreds of ad variants a month, where the audio step is the bottleneck.

Haaze 2
The enhanced Haaze v2 by Klevgrand offers a sophisticated approach to managing stereo width and spatially positioning sounds within a stereo mix. Traditional left-right panning often falls short of mimicking real-world acoustics, which becomes evident when attempting to place a mono sound seamlessly in a stereo environment, particularly when using headphones, as the outcome tends to sound overly "mono." The Haaze plugin enhances audio positioning, making it feel more intuitive and enjoyable for listeners. It achieves this by dividing the audio signal into 16 distinct frequency bands, allowing users to delay the left or right signal within each band to create an effect that tricks the listener into perceiving sound from the direction of the signal that arrives first. Additionally, users can pan sounds left or right and alter the overall width of each band, such as keeping lower frequencies more centered while allowing higher frequencies to spread wider. Haaze is also capable of diffusing a mono signal, broadening its spatial presence. If this concept appears intricate, it ultimately leads to a richer listening experience.
