Teac has released a two-channel waveform editor for Mac and Windows operating systems. The unusual thing about this editor is the program also can convert waveform content between PCM and DSD formats. +++ HERE +++ is a link with more details and the download link.

Looks good, but I see no download for the software, only for the manual.

Well shucks, that's a bummer. It appears the software download link has been removed from the box that HAD links to the software and the manual. Sorry for the false alarm Sinbad.

No problem Jim. I thought it could be something to do with country of residence so I tried Europe, no go, then Japan, and Bingo..

Chris,

Thanks for posting a link. It's nice to know the editor is still available. It had me worried for awhile.
