If you say “Yes” to that question, Orpheus works as normal, but if you say “No” you will see the error message. ”Do you want to allow Orpheus access to the Camera” (this question is asked, whether the Mac has a camera or not). This is caused by replying “Don’t Allow” to a message that Mojave asks fairly commonly when it first opens some programs. Security settings in Mojave and Catalina and higherĪn error message “AVCCommand result = 0xe00002be” has been reported by some users who are running Mojave or Catalina, when trying to open the Orpheus Control App. Under Catalina, Apple now disallows the use of 32bit Apps, so you must use the 64bit v1.10 app on Catalina, and the 32bit 1.07 app on earier versions of MacOS. The Control app allows you to change settings on Orpheus. The driver for Orpheus is part of MacOS, and is supplied and updated by Apple, so you will find that when connected, Orpheus appears in Audio MIDI setup and you can play and record audio through it. Pending ongoing work with Audinate for our Dante capability, we expect to have a native M1 silicon app out later this year.įor MacOS Monterey, Catalina (+ Big Sur), please read below.
The Prism Sound X-Platform Atlas, Titan and Lyra products continue to work on Apple Mac operating systems under the Rosetta 2 bridge. If anything changes we will post it here. Currently OS Ventura does not support core audio over firewire so the Orpheus, and multiple other devices, will not work.

Link to Prism Sound Logging and Transcription site Link to Prism Sound Test and Measurement site Gain scaling would show up as noise floor modulation.Jobs, careers and opportunities at Prism Sound There may be other gotcha's but this was enough for me to abandon it a couple decades ago.īench performance could be gamed with transparent gain scaling (before/after).
This nonlinearity some 20dB above the quantization floor, is not likely to sound very bad but as usual no free lunch. Imagine if one LSB of the top convertor represents 4 bits or more (24dB) in the lower convertor. What isn't obvious is that the upper convertor linearity has to far exceed it standard linearity (for that number of bits) so the combined digital output is monotonic.
I looked into that decades ago because it seems like an inexpensive way to extend dynamic resolution (level shift audio N dB between two convertors then seamlessly combine the digital output to buy extra bits of resolution. Click to expand.Funny, I was going to mention that several days ago but decided to not clutter up the thread while somebody might still present objective information.
