Meeting Highlights Jon Tatooles and Paul Isaacs presented �Sound-for-Picture Recording with File-Based Digital Multi-Track Recorders� on behalf of Sound Devices, LLC to approximately 60 members of the Chicago AES chapter. Jon Tatooles is co-founder and Managing Director and Paul Isaacs is a Principal Applications Engineer. Sound Devices was started in 1998 with a focus on sound-for-picture equipment. Jon began by discussing the need for equipment such as the Sound Devices 788T. A dual-system for with a video camera and sound equipment is typically used which allows for multitrack recording. Multitrack recording is essential for unscripted reality-style production, live sound, surround recording and reduces the need for ADR. This requires timecode and a slate synch to allow post-production to easily piece everything together. Jon then discussed the new 788 and competition. All such devices record to WAV and Broadcast Wave (BWAV) file formats. WAV includes audio + metadata (sampling rate, bit depth, track count, non-audio information). BWAV includes all of this plus some specialized data for the sound-for-picture field including time code, editorial workflow and track names. The 788 can write to hard-drive, solid state drive (preferred!) and optical disc simultaneously. 788T panel presented showing controls, sync I/O, GPIO, CF slot, etc. Sound Devices decided to use the standardized Sony camera batter mount because of how common it is. Jon pointed out the interesting fact that in LA the fire marshal requires by law that no one is electrically tethered to anyone else, thus requiring all mics be wireless. Paul presented the Wave Agent software designed specifically for use in the sound-for-picture field. Wave Agent imports any WAV file and pulls out all metadata letting the user view and edit information such as track history and titles and has the ability to convert between mono and poly files. By visiting sounddevices.com/calculator one can access their online software to gauge the required memory for a specified recording time. The Chicago AES chapter would like to thank Jon and Paul for the interesting and informative presentation.
