Composer, Producer & Mixer

Walder Martinez on SoundBetter

Award-winning composer creating original orchestral and cinematic music for film, television and games. Memorable themes, expressive arrangements and storytelling-led production, alongside music mixing and mastering.

Every story has its own sound.

I'm Walder Martinez, a composer, producer and mixing engineer based in Málaga, Spain, working internationally. Music production since 1990; sound post-production since 2001.

My original score for Némesis received the Best Music award at the 7th Independent and Experimental Short Film Festival of Kerala. I also handled the film's complete sound post-production.

My creative focus is original orchestral and cinematic music: memorable melodies, thematic development and arrangements that serve the emotion and narrative of a scene. I'm particularly interested in films where music is integral to the storytelling.

Meet Again, my featured sample, is an original orchestral composition that I composed and mixed. It represents the symphonic, melody-led direction I want to bring to new film projects.

Services: original scoring, orchestral composition, instrumental production, music mixing and mastering, plus audiovisual sound design and re-recording mixing.

Other credits include MechWest (re-recording mixing), My 7 Grandmas, Sins of David (2024) and Perros del Fin del Mundo.

Interview with Walder Martinez

  1. Q: How would you describe your style?

  2. A: Symphonic and melody-led, with an emphasis on emotional storytelling and thematic development. I want the music to have its own identity while supporting the characters, pacing and dramatic intention of the project.

  3. Q: What other musicians or music production professionals inspire you?

  4. A: John Williams is an important reference for the orchestral film music I aspire to write, especially its memorable themes and the way musical ideas develop with the story. I use that inspiration as a starting point for original music, not imitation.

  5. Q: Tell us about a project you worked on you are especially proud of and why. What was your role?

  6. A: Némesis, for which I composed the original score and handled the complete sound post-production. It brought music and sound together in service of the story, and the score received the Best Music award at the 7th Independent and Experimental Short Film Festival of Kerala.

  7. Q: What questions do you ask prospective clients?

  8. A: What is the creative goal? Who is the audience? Which references best represent your direction? What material is available, what deliverables do you need, and what are the deadline and budget?

  9. Q: What advice do you have for a customer looking to hire a provider like you?

  10. A: Listen to relevant samples and describe the result you are looking for, not just the tools you expect someone to use. Share references, your deadline and the available material so we can establish a clear scope before starting.

  11. Q: What was your career path? How long have you been doing this?

  12. A: I've worked in music production since 1990 and sound post-production since 2001. My work brings together composition, production, editing and mixing, with collaborations across international music and audiovisual projects.

  13. Q: What type of music do you usually work on?

  14. A: My main creative interest is original orchestral and cinematic music, with a focus on melody and thematic development. Meet Again, the sample on my profile, is an original piece that illustrates that direction. I also offer instrumental production, music mixing and mastering.

  15. Q: What do you bring to a song?

  16. A: A composer's perspective and a mixer’s attention to detail. I focus on the emotional intention, the relationship between the instruments and the space each element needs, while preserving the identity of the music.

  17. Q: What's your typical work process?

  18. A: We start with the brief, references and intended audience. I review the source material and agree on scope, deliverables and timing. For composition, we establish a musical direction before developing the arrangement; for mixing, we identify the priorities of the song. Feedback and revisions stay focused on the agreed direction.

  19. Q: Tell us about your studio setup.

  20. A: I work from La Galera Studio in Málaga, Spain, using Steinberg Nuendo and Avid Pro Tools Ultimate for composition, editing and mixing. The setup supports both music production and audiovisual post-production.

  21. Q: Describe the most common type of work you do for your clients.

  22. A: Original composition, instrumental production, music mixing and mastering. I also work on film and animation soundtracks, including sound design, dialogue editing and re-recording mixing.
