I am using windows XP Pro, 32bit, Service Pack 3. Audacity Version 2.0.6-alpha compiled with ASIO Support. I followed the instruction to manually compile ASIO Streaming within audacity.
My computer is Win XP, Intel Core 2 Duo @ 2.8Gb, 4Gb Ram.
Audio Interface is MOTU 2408 Mk1 to PCI 324 interface card.
I am recording 24 channels at 48k via the 3 optical ADAT connections on the back on the 2408. I have found that there is a clicking noise or sound across all of the tracks at about -40db in the mixer meter. I can select a track that did not have an input, normalize and see the noise, sound, disturbance. I have also noticed that there is a small delay in the sound from track to track.
I have attached a file with the sound I get. hopefully someone will know what this is and have some idea how I can get rid of it.
I can record less than 24 tracks, however 24 tracks is the most available that I can choose to record with my current hardware i/o setup. I have tried lowering the sampling rate but that brings other issues due to the input signal is 48k.
The system has 4 Gb of RAM and 2 Gb available during recording. CPU usage is running around 60% with peaks of 80% when the OS has a task to do.
Thank you for your concern about using XP. This computer is used just for recording, playback and a rough mix of the tracks. It is not “online” or attached to a network. File transfers are all done using USB or Firewire interface. Media is scanned on another computer WIn 8.1 or OSX Mavericks prior to use.
