This move takes the brand, created by Studio Audio and Video Limited, out of the control of the administrators with whom it was placed on 15 February.
Prism Sound makes interfaces and converters for the recording and broadcast markets.
The company will now offer a broader portfolio of high-end audio production tools to the market including the Sadie digital audio workstations and Prism Sound's A/D and D/A converters for mastering, tracking and post production.
Prism Sound's joint director Graham Boswell said: “Prism Sound is financially secure and in an ideal position to take on the Sadie brand.”
Boswell added: “By combining two complementary product ranges with overlapping customer bases, we are confident that we can create a highly competitive business.”
The Sadie brand name will be retained as part of the Prism Sound business.
Existing Sadie customers will have full access to product support and can use the same numbers and email addresses. New orders are being accepted by Prism Sound's sales offices in Cambridge.
Although deliveries will resume almost immediately, availability of certain products may be limited initially as a result of reduced stock during the administration period.
PC-based Sadie craft editors are used by, among others, BBC radio and music.
Studio Audio and Video Limited was established in 1991 and was based in Cambridgeshire.
