Hi Folks From Wikipedia [edit] Limitations The WAV format is limited to files that are less than 4 GiB in size, because of its use of a 32-bit unsigned integer to record the file size header (some programs limit the file size to 2-4 GiB).[3] Although this is equivalent to about 6.8 hours of CD-quality audio (44.1 kHz, 16-bit stereo), it is sometimes necessary to exceed this limit, especially when greater sampling rates or bit resolutions are required. The W64 format was therefore created for use in Sound Forge. Its 64-bit header allows for much longer recording times. The RF64 format specified by the European Broadcasting Union has also been created to solve this problem. If you record your wav files as non interleaved i.e. left and right, you can double your recording time Cheers -pm -----Original Message----- From: Association for Recorded Sound Discussion List [mailto:[log in to unmask]] On Behalf Of Tom Fine Sent: Thu 19 Nov 2009 14:24 To: [log in to unmask] Subject: Re: [ARSCLIST] Sound Forge issues Hi Graeme: I think there was also some limit in older versions of SoundForge, but I do not know this for a fact. With SoundForge 7, I ran into the same 2 gig limit running Win2K with NTFS discs. I specifically ran up against this transferring 3.75 IPS 1-mil 2-channel tapes (90 minutes per direction). Files had to be cut to 58 minutes or less of 96/24 2-channel. I have that old workstation running other duties and I just verified that it's got NTFS on all the hard drives I was using (I'd save to internal D drive first, then back up to external USB drive). So later versions of SoundForge may now be limited only by disc size in a NTFS system. I'm about to start a project with some long-duration tapes so I will test this out. -- Tom Fine ----- Original Message ----- From: "Graeme Jaye" <[log in to unmask]> To: <[log in to unmask]> Sent: Thursday, November 19, 2009 8:11 AM Subject: Re: [ARSCLIST] Sound Forge issues > Hi Association > > On 19/11/2009 Tom Fine wrote; > > TF> ... 2gig seems to be the limit, not time of audio. > > Yes, that's right.
