Recording and Acquisition : Getting Audio into Pyramix Virtual Studio
7 - 147
Getting Audio into Pyramix Virtual Studio
There are four primary methods of getting audio into Pyramix: You can record audio directly into the Timeline of a
Pyramix Editing Project, record audio using a Digitizing Session, use Background Recorders or you can import
audio files existing previously.
Please see also: Digitizing Sessions on page 165, Background Recorders on page 149 and Importing
Audio Files into Pyramix Virtual Studio on page 162.
Check Sync
Before attempting to record any audio please check Pyramix and the audio source(s) are synchronized as you
intend.
MassCore
Verify PTP sync (green) under RAVENNA.
Native
Project sampling rate should match ASIO interface sampling rate.
File Format and Disk Limitations
File Size Limitations
By design legacy SD2, WAV or BWF files are limited to a maximum of 2GB due to their 32bit signed addressing
(thus 31 available bits) formats, while 32bits unsigned addressing AIF files are limited to 4GB. Please keep this in
mind when recording and/or exporting to any of these formats, the 2GB/4GB limit might in fact be quite close,
particularly when working with high sample rate multitrack files.
As a comparison, Pyramix, thanks to its own PMF 64bit addressing file format, can generate PMF files of virtually
limitless size. This makes it the file type of choice for creating single file, large multitrack projects at high sampling
rates.
The WAV file format can now accommodate RIFF64 removing the 2GB limitation. Please see: WAV and BWF on
page 471
Hard Drive Limitations
A very similar 2GB/4GB* limit can also be encountered the hard way when attempting to write large files, even in
PMF format, onto storage units (hard drives, memory cards etc.) formatted using an old 32bit file system such as
FAT32 or HFS.
Yet another, higher, limitation also exists with IDE ATA/ATAPI drives. This will show up at around 137GB. This may
be caused by part of a system (drivers, controllers and/or old Windows version) only recognizing the 28bit
addressing of the original ATA specifications, and not the enhanced 48bits available on newer equipment. This is
usually solved by installing fresh and or updated Bios/Drivers/OS.
*The official limit is 4GB, but serious trouble can start at around 2GB.
Pyramix audio file format
Unless there is a good reason for using another file format for recordings we strongly recommend using the
default .PMF file format. This will give the best performance in a number of key areas. For further information
please see: Optimizing Pyramix on page 653
Recording Audio into a Pyramix Virtual Studio Project
Start a new Project, or open an existing one. Make certain the Mixer sample rate and sync source is set as desired.
You will need to configure at least the same number of Mixer channels as Tracks you wish to record.
Before beginning audio capture, check or select appropriate record settings. Open the Settings > All Settings >
Project > Record page (alternatively use the keyboard short-cut Ctrl - f and click the Record Tab) There are many
settings in this dialog page, but for now you need only be concerned with; Destination Drive (Media File folder),
