Hello there! I'm a podcast producer and mastering engineer, graduated from SAE Institute Mexico. I collaborate with “La Casa de La Sal A.C.”, where I focus on audio recording for interviews and podcasts, as well as post-production. I completed my training at Grupo ACIR, where I focused on the development of mass-produced radio spots. Additionally, I created bumpers for special programs ("Tríos y Boleros"). I participated on numerous occasions as a production assistant in Pro Tools for the recording of podcasts with Maca Carriedo, Charo Fernández, and other radio personalities.
FAQ
How should you send me the files?
You can use the attachment in the inbox messages, or the easiest way is to upload all the files to wetransfer.com (via download link) and paste the link in our inbox chat. You can also use Dropbox and share the folder via download link as well.
What do I deliver to you?
A high quality WAV/mp3 44.1/48 kHz 24bit file (CD/DVD/Spotify/Youtube/Streaming standard)
What format should the files have (for mastering services)?
16 bit or 24 bit WAV files. AIFF files work. No mp3's. Please make sure there is no limiter on your master/stereo out, and that there is at least a 3 dB's of headroom and no clipping. Ensuring it's not too loud will help a lot with the final master.
