In the world of audio post-production, remote recording, and voice-over work, two technologies have revolutionized the way professionals collaborate and deliver high-quality audio: Source Connect and ISDN. While they may seem like obscure terms to outsiders, these technologies have been the backbone of the industry for decades. In this article, we’ll delve into the world of Source Connect and ISDN, exploring their history, functionality, and applications.
A Brief History of ISDN
To understand the significance of Source Connect and ISDN, it’s essential to take a step back and look at the evolution of remote recording technology. In the 1980s, the audio post-production industry was plagued by the limitations of traditional phone lines. The quality of audio transmitted over phone lines was often poor, making it difficult for professionals to work remotely.
The introduction of Integrated Services Digital Network (ISDN) in the 1990s changed the game. ISDN was a digital telecommunications standard that allowed for high-quality, low-latency audio transmission over phone lines. This technology enabled professionals to record and transmit audio in real-time, making remote collaboration a reality.
ISDN quickly became the industry standard for remote recording, and its popularity soared in the 1990s and early 2000s. However, as technology advanced and internet connectivity improved, ISDN began to show its limitations.
The Rise of Source Connect
In the mid-2000s, a new technology emerged to challenge ISDN’s dominance: Source Connect. Developed by Source Elements, Source Connect is a software-based solution that allows for high-quality, low-latency audio transmission over the internet.
Source Connect uses a proprietary algorithm to compress and transmit audio in real-time, making it possible to record and collaborate remotely with minimal latency. This technology was a game-changer for the industry, as it offered a more flexible and cost-effective alternative to ISDN.
