What Is A Transient In Audio? What Is Pre-Ringing?
What Is a Transient in Audio? Rob Watts Talks Pre-Ringing on The Occasional Podcast
What is a transient? What is pre-ringing? If you have spent much time reading DAC reviews or following discussions about digital audio, you have probably encountered both terms. You may also have encountered explanations that leave you wondering whether enjoying your favorite album now requires an engineering degree. The latest episode of The Occasional Podcast offers a more inviting place to start: an interview with Rob Watts, the digital audio designer associated with Chord Electronics.
Here is an opportunity to explore two subjects that regularly surface in conversations about high-fidelity sound with someone whose work puts digital playback under a microscope.
What Is a Transient, and Why Do Audiophiles Keep Talking About It?
Audiophile vocabulary has a way of expanding faster than the space on an equipment rack. We talk about speed, texture, separation, timing and realism, sometimes assuming everyone has agreed on what those words mean. Audio transients belong in that conversation, but understanding the terminology takes more than spotting it in a review.
Think about the recordings you use to evaluate a system. Perhaps you reach for piano, percussion, acoustic guitar or a familiar voice. What makes one presentation feel convincing? Which details catch your attention, and which descriptions actually help explain what you hear?
Those questions provide useful motivation for exploring transients in audio. They also point toward the appeal of this episode. Rather than treating another technical phrase as something to memorize, listeners can approach it through their interest in music and the equipment that reproduces it.
We will leave the full answer to “what is a transient?” for the podcast. Hearing the explanation in the context of a conversation gives the subject more room than a quick glossary entry, when the guest has spent years working on digital audio design.
What Is Pre-Ringing? A Question Worth Taking Beyond the Forums
Then there is pre-ringing, a term that sounds slightly like something your phone does before delivering another unwanted sales call. In hi-fi discussions, however, it opens the door to a much more interesting set of questions.
Why does pre-ringing appear in conversations about digital filters? What should listeners understand before drawing conclusions from a waveform? How do we connect technical descriptions with the experience of sitting down and listening to an album?
These are good questions to bring to the Rob Watts interview. They are also reasons to resist deciding that a complicated topic can be settled by a single picture, a specification or the loudest comment underneath a product announcement.
If you arrived here searching “what is pre ringing,” make the episode your next stop. The goal is to give the subject a proper hearing, with the explanation and perspective that a longer conversation allows. We are keeping the technical reveal in the episode, where it belongs.
Rob Watts and the Bigger Digital Audio Conversation
Watts is familiar to many headphone enthusiasts and listeners through his work with Chord Electronics, including the DAVE DAC. His perspective makes this interview an appealing listen for anyone interested in the thinking behind digital playback.
Rob also talks about a wide range of other subjects on the show, including what Chord Electronics has been up to the past 5 years, and what they also have coming up on the horizon.
Keep Listening: Season 15 and Season 14
After the Rob Watts interview, spend some time with the rest of Season 15. Jason Stoddard of Schiit Audio joins the show for “Raising The Floor,” a conversation about expectations and possibilities at the affordable end of hi-fi. Jazz pianist Miki Yamanaka offers another perspective, discussing her album Breathe alongside sound, recording, performance and listening.
Season 14 provides plenty of reasons to continue exploring. Look for interviews with John Siau of Benchmark Media Systems, AudioQuest’s Bill Low, Julie Mullins and Robert Harley. The season also includes speaker selections and coverage of AXPONA and HIGH END Vienna, offering a mix of design perspectives, listening impressions and discoveries from the show circuit.
