GeoVENN AUDIO
client work

GeoVENN AUDIO designs what a store sounds like: background music libraries, weekly radio-style promotions and the schedules that play them on every speaker. These are recent deliveries for supermarkets, a retail chain and a museum.

How these are made. This work is AI-assisted, and I run it end to end. I adapt the copy, write the music prompts and pick the best take from many generations (Suno), then cast and direct the AI voices (ElevenLabs). Last, I edit, mix and master each spot to a loudness spec set per client. Every week I judge whether a generated track really fits the brief, its genre and its mood before it reaches a client.

02 · Film & visual

Music for picture

An ongoing commercial client in real-estate film, plus scores for independent short films, all three recognized at film festivals. Each cue was composed and produced by me under my studio name, JP's Music Studio™.

CONSORCIO de Planeación Inmobiliaria

Real-estate development · Nuevo León & Guanajuato, México

For the last 22 months I have been the composer for CONSORCIO's video content. I work alongside their video team, who shoot the drone and ground footage, and their post-production and visual-effects team, who build the 3D renders and graphics. Every piece is scored to picture. The music is built in 4-bar blocks so each swell, drop and logo reveal lands on a cut. So far that adds up to 170+ video renders, plus land surveys, neighborhood films and construction progress reports.

Brand audio &
commercials

Audio logos, openers and commercial beds for companies, podcasts, creators and events. These pieces range from 8 seconds to about a minute. Each one has to say who the brand is before the logo finishes animating.

04 · Songwriting & composition

Songs & concert music

Original songs with English lyrics, an arrangement, electronic and lo-fi productions, and written scores for orchestra and string quintet. Scores and lyric sheets are linked where they exist.

From concept to finished master

I studied composition at Universidad Panamericana. My professional exam portfolio (September 2023) held 1 h 34 min of original music: concert works, film scores and advertising. Since then I have built GeoVENN AUDIO, where AI generation is one tool inside a full production chain. That chain runs from brief and copy through music direction, voice direction, editing, mixing and mastering, delivery and scheduling.

Genres I write and produce

  • Pop, R&B and singer-songwriter ballads
  • Electronic, lo-fi, trap and progressive rock blends
  • Latin pop, Tex-Mex and Texas country (commercial)
  • Orchestral, chamber and cinematic scoring

Tools

  • FL Studio, REAPER, Sibelius, Adobe Premiere Pro
  • Suno and ElevenLabs inside a scripted production workflow
  • Loudness-targeted mixing and mastering (LUFS) for retail and broadcast
Let's work together

Music that fits the brief, from the first listen.
