I do voice-overs in my home studio in Spain. At home I use the software Adobe Adobe Audition, Neumann TLM 103 and SE Electronics Z3300A condenser microphones, SE Reflexion Filter and Genelec 8040 speakers. I send a few versions of the audio as mp3 or wav file.

For recording of national commercials I use the studio Alta Frecuencia in Sevilla. At this excellent studio an ISDN connection is possible.
