Pro Audio DSP is composed of Paul Frindle and Paul Ryder.

Paul Frindle has 40 years of experience in the pro audio and music industries. He has been part of the development of some of the most beloved products in recording history, including the SSL E and G-series analog consoles, the Sony Oxford digital mixing console and more recently the Oxford Plugins (which later became Sonnox). On leaving Sony Oxford, he co-founded Pro Audio DSP in order to make novel sound-processing applications to fulfill many issues he had identified in the audio production chain over his career.

Paul Ryder is a software developer and musician with 10 years' experience in the pro audio industry. During this time, Paul was a key member of the development team for the Sony OXF-R3 console. He was also the principal software engineer responsible for the development and implementation of the Sony Oxford plugins.

    This has been a secret weapon of mine for note-by-note consistency on bass and frequency aligning vocals for a few years. It is utterly unique and quite often life saving.

    This is one of the best multi-band compressors I have come across. It deals with phase issues, which makes it worth its weight in gold.
