The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.In episode 139 of the THD Podcast, Dr F Joseph Pompei, the founder of Holosonics, joins to introduce how they modulate ultrasonic frequencies to create localized 'audio spotlights'.Holosonics is a pioneer in highly targeted sound through its patented Audio Spotlight technology. Unlike traditional speakers that broadcast sound in all directions, Holosonics creates a narrow, flashlight-like beam of audio. The system operates by converting audio into ultrasonic waves, which have wavelengths only a few millimeters long. Because these waves are so small, they naturally travel in a laser-like path. As this silent, modulated ultrasound travels through the air, it interacts with air molecules, naturally demodulating into audible sound precisely along its path. Step one foot outside the beam, and the audio vanishes.Check out the podcast on @YouTube @Spotify @amazonmusic @iHeartRadio @RumbleVideo @Apple @GoogleThanks to Barry Vogel and the ALTI Audio & Loudspeaker Technologies International for their support as well!Thanks to AudioXpress for their support on this episode as well!#audioengineering #acoustics #Holosonics #AudioSpotlight #DirectionalAudio #DirectionalSound #ParametricSpeaker #FocusedSound #UltrasonicSoundPlease like, subscribe, share, and comment with your feedback!

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.In episode 137 of the THD Podcast, Tony Doy and Phillip Muehring from Triad Semiconductor join to introduce the Universal Audio Analog Front End (AFE) TS5510.The TS5510 is a two-channel, high-performance Universal Analog Front End (AFE) developed by Triad Semiconductor. It is designed to bridge the gap between high-level line signals and low-level microphone inputs for modern audio systems, particularly professional mixing consoles and recording equipment. Basically, you can run mics directly into a mixer without a preamp. The TS5510 is a dual-channel analog front end that simplifies audio hardware design by replacing traditional, complex input stages with a "universal" signal path. Its unique current-conveyor architecture allows a single input to handle everything from low-level microphones to high-output instruments without needing mechanical switches or pads, while its massive 156 dB capture range makes it the ideal partner for 32-bit float recording systems to eliminate clipping. By integrating high-precision digital gain control and superior noise rejection into a compact chip, it enables manufacturers to build smaller, more reliable professional mixers, field recorders, and audio interfaces with a significantly reduced part count.

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.In episode 112 of the THD Podcast, Pauli Minnaar and Ivan Sandager from IDUN Audio join to tell us about their very cool spatial audio technology and how it creates a new dimension in listening. The way we use sound is changing. We are increasingly listening to digital media. This is driven by an exponential growth in audio content from online meetings, phone calls, podcasts, audio books, music movies, gaming, virtual- and augmented reality (VR/AR) and the metaverse. Soon we’ll be wearing headphones most of the time. But listening with traditional headphones can be very tiring! This is mainly because the sound appears to be inside our heads - an unnatural experience that we have come to accept.During everyday listening, however, we can hear where sound is coming from, how far away things are, and what space we are in. Currently, when listening with headphones, these amazing hearing abilities are lost. That is why IDUN audio has developed dynamic spatial audio (DSA) software - to restore natural hearing when listening with headphones.Check out the podcast on  @YouTube   @Spotify   @amazonmusic   @iHeartRadio   @RumbleVideo   @Apple   @Google  Thanks to Barry Vogel and the ALTI Audio & Loudspeaker Technologies International for their support as well!Thanks to AudioXpress for their co-promotion on this episode as well!#audioengineering #acoustics #audioPlease like, subscribe, share, and comment with your feedback!

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 99, Dr Sean Olive from Harman International joins to explain the background and the rationale behind the Harman Headphone Target Curve. Some fascinating discussions on the evolution and some of the test procedures using scientific controls to produce a statistically significant study. Ultimately, it produces a line of fit between the listening experience and the frequency response to give headphone developers a target curve that satisfies most users. Notes from the question at 41:45 from Sean Olive: "I thought a bit more about the question Simon asked whether the target curve should be different for IE vs OE/AE types and wanted to clarify in case I misunderstood the question. He (Simon) seemed to think they should be different but perhaps he was referring to differences between targets for Type 3,3 versus Type 4.3 -- not headphone types? The baseline targets for IE and OE/AE were the same for Type 3.3 before adjustments to bass and treble were made. The baseline was determined by measuring a flat in-room speaker system. We found the IE target had about 4 dB more bass than the AE/OE target and only slightly different in treble. The same baseline for IE/ AE/OE is determined by measuring the speakers in the same room with Type 4.3 HATS. But after adjustments, I believe the IE/OE/AE will be closer than the Type 3,3 particularly in the bass b/c of the larger volume and acoustic impedance of the Type 4.3 vs 3.3. Will the headphone targets for Type 4.3 versus 3,3 be different? Absolutely, because the response and acoustic impedances are different. The main differences will be below 200 Hz and above 3-4 kHz. Hopefully, that clarifies my response to this question, if I understood it correctly."

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 96, Stefan Liebich of Elevear joins to discuss their audio algorithms for hearables that cover occlusion, idle noise, and immersive 3D audio. Developed over many years and now being commercialized with key silicon partners. OCCLEAR® TECHNOLOGY NATURAL OWN VOICE THROUGH OCCLUSION CANCELLATION Existing headphones isolate the user from the environment, making their voice sound boomy and unnatural to them. This phenomenon is due to the occlusion effect, which attenuates air-conducted sound while amplifying body-conducted sound. A headphone user who is unhappy with the unnatural sound of their own voice. A headphone user who enjoys a natural own-voice sound thanks to the Occlear® technology. Our Occlear® technology eliminates the occlusion effect, allowing hearables users to perceive their voice and environment with natural clarity. Occlear® requires no specialized hardware and can be integrated seamlessly into ANC-ready hearables via a simple firmware update. IDLE NOISE REDUCTION TECHNOLOGY WORLD-CLASS HISS-FREE TRANSPARENCY FOR YOUR HEARABLE Hearables users often complain about microphone noise or hiss when using transparency mode. It stems from the low-cost, miniature microphones used in today’s hearables. To mitigate this noise, manufacturers often limit the bandwidth of their transparency mode, compromising the clarity of the sound. Our patented Idle Noise Reduction (INR) technology reduces the noise floor of hearable microphones by 10–15 dB, matching the performance of high-end studio microphones. The INR removes the hiss, allowing hearables manufacturers to achieve world-class transparency with low-cost components. IMMERSIVE 3D AUDIO TECHNOLOGY INSTANT, UNALTERED 3D AUDIO WITHOUT LATENCY OR DISTORTION Existing spatial audio solutions often struggle with head movement, resulting in a lag that disrupts the immersive experience. They also tend to compromise sound quality by adding reverb. With imperceptible motion-to-sound latency, our algorithms ensure that the audio keeps pace with your every move. This seamless integration means you experience the world of sound most naturally as you navigate through it. Experience unaltered, high-fidelity audio that runs directly on your hearable device—no need for complex stack adjustments, including Bluetooth and app dependencies.
