EDIUS can edit audio down the the frame level. You can easily split the audio into left and right channels, pan the audio left to right, and ramp the level up and down.
It can also handle audio with up to 16 audio tracks which you can add to the timeline en-masse. EDIUS does not do surround sound mixing, however, if you set up the project correctly and already have a surround sound mix, EDIUS can write this to disc or make a Dolby Digital file for use else where (information on how to do this is included in our tutorial discs)Adobe Premiere Pro
has more advanced sound editing, as does Sony Vegas
, with both editing down to the sample level, with surround sound, and with tracks that can be routed to different buses and have effects applied on a track or clip level. EDIUS sound editing is comparable to Avid Media Composer
,Apple Final Cut Pro
or Adobe Premiere 6
(the latter is no longer available, having been replaced by Premiere Pro a few years ago, but it may help you to gauge the level of EDIUS' audio editing).EDIUS also has a good voiceover tool, which lets you play the timeline and record to a track whilst doing so, and support for VST plug-ins
which means there is a huge range of possible add-on effects available.
