When shopping for an electric vehicle, affordability is becoming a more common trait. But affordable and energy efficient is truly a rare breed. Often you have to sacrifice one for the other. Want something affordable? Great, here's a range loser. Want something that goes the distance? Be ready to pay the price. Surprisingly, here comes […]

A build log on ESP, six VST3 plugins written in C++ with JUCE 8 and shipped through a store I built myself. What the framework does for you, where it stops, and the one measurement that changed how I work. The line Six plugins, all JUCE 8, all VST3 plus standalone, all GPL v3, all downloadable from esp-plugin-store.vercel.app : Plugin What it is Basic Oscilator three oscillators on juce::dsp , the first thing I ever built, kept honestly VERTEX dynamic range compressor with a live transfer curve ESP-L1 brick-wall limiter with pre and post spectrum overlay MEGACRUSHER distortion, saturation and bit-crusher, three algorithms SPECTRUM real-time analyser, 2048-point FFT, spectrogram and 3D waterfall SYNTH/1 16-voice wavetable synth, unison, step sequencer, FX rack, interactive EQ That table is in the order I wrote them, and the order matters more than any single plugin. Each one starts roughly where the previous one ran out of framework. What juce::dsp actually hands you Basic Oscilator is three oscillators, three LFOs, a bit-crusher and a master gain. Almost all of it is the juce::dsp module doing the work: juce :: dsp :: ProcessSpec spec ; spec . maximumBlockSize = ( juce :: uint32 ) samplesPerBlock ; spec . sampleRate = sampleRate ; spec . numChannels = ( juce :: uint32 ) getTotalNumOutputChannels (); for ( int i = 0 ; i < 3 ; ++ i ) { oscillators [ i ]. prepare ( spec ); lfos [ i ]. prepare ( spec ); lfos [ i ]. initialise ([]( float x ) { return std :: sin ( x ); }); } masterGain . prepare ( spec ); That is the whole contract of the module. Prepare everything with one ProcessSpec , wrap your buffer in an AudioBlock , hand it to a processor as a context: juce :: dsp :: AudioBlock < float > block { tempBuffer }; oscillators [ i ]. process ( juce :: dsp :: ProcessContextReplacing < float > ( block )); juce::dsp::Oscillator takes its waveform as a lambda, so the three waves are three one-liners: case 0 : osc . initialise ([]( float x ) { return std :: sin ( x ); }); //

Last September, Steve Ballmer insisted in an ESPN interview that the Clippers weren't involved in a shady-looking $28 million endorsement deal for his star player, Kawhi Leonard, that involved no actual endorsing. Now, the former Microsoft CEO has been suspended by the NBA for a year, while the league says his team will forfeit five […]

In what could be fortuitous timing for hearing aid users, Anker announced its first over-the-counter (OTC) hearing aids at IFA 2026. It was only a couple months ago when LXE Hearing, the parent company for Eargo and Lexie Hearing - two major OTC manufacturers in the US - decided to end US operations and exit […]

Anker's SleepLab speaker promises to track and enhance sleep without a wearable. It uses millimeter-wave radar (60GHz) blasting from your nightstand to track micro-movements in your chest and body to continuously monitor your heart rate and breathing to enhance whatever sleep stage you're in. It also embeds lots of hippie shit. If I'm understanding things […]

Sony announced three new tower-style party speakers that will now be the largest options in its ULT Power Sound lineup. The new ULT Tower Max, ULT Tower 7, and ULT Tower 5 all feature expanded connectivity including USB-C, RCA, and XLR ports for connecting to audio gear using physical cables. The new models also come […]

Sonos is cramming AI into its software because it’s “very hot these days.” The new features, which include agentic automation, are opt-in.

JBL is well known for its portable bluetooth and party speakers, but now it's also stepping into the world of connected whole-home audio. The JBL Cove series of speakers introduced today can work independently, as a stereo pair, or linked together to form a multi-room sound system, placing the range in competition with Sonos and […]

The flagship headphones get up to 57 hours of battery life and have easily replaceable batteries.

Outstanding call quality and an excellent price point put these earbuds way ahead of pricier competition.

📝 Originally published (in Japanese) at forge.workstyle.tech . When building voice-based AI interactions in the browser (avatars, voice bots, streaming AI), you’ll inevitably hit pitfalls stemming from audio physics and browser implementation quirks. This article compiles 16 traps I encountered during product development , organized in a symptom → cause → solution lookup format . No need to read from top to bottom—jump straight to the symptom you’re facing. Echo and Self-Response Issues 1. Avatar Responds to Its Own Voice (Despite echoCancellation: true ) Symptom : TTS audio is picked up by the mic, and STT recognizes it as user speech, creating a self-response loop. Cause : AEC (Acoustic Echo Cancellation) requires a reference signal (the "sound to cancel"). Only the browser's official playback paths ( <audio> / WebRTC receiver tracks) serve as references. Custom playback via Web Audio API does not reliably function as a reference . Solution : Return TTS audio from the server as a WebRTC remote track and play it via an <audio> element. This eliminates echoes without text-matching workarounds (tested: 99 seconds of continuous speech with speakers on, zero false user turn detections). 2. Echoes Are Gone, but Speaking Simultaneously with the Avatar Distorts My Voice and Causes Misrecognition Symptom : Only during dual speech, proper nouns get mangled (e.g., "社員数" → "シャインズ"), especially at word beginnings. Cause : Fundamental AEC trade-off. To cancel echoes, AEC suppresses/distorts near-end (user) audio during dual speech. Solution : Mitigate in three layers: ① Increase mic Opus bitrate and enable FEC (see Pitfall 13) ② Provide vocabulary hints to STT (see separate article: use "recent avatar speech" as initial_prompt , not a dictionary) ③ Instruct LLM: "Input is STT transcription with potential errors. Interpret unnatural words as phonetically similar terms and add confirmation prompts." 3. Can’t Suppress Audio from Other Apps (Music, Videos) Symptom : Audio/lyrics fr

Two audio players do not make a fair before-and-after test. If the second player restarts from zero or takes half a second to load, the user is no longer comparing two versions of the same moment. They are comparing two memories. That is a weak way to evaluate any audio effect. It is especially weak for AI processing. A denoiser can remove a fan while softening consonants. A de-reverb model can reduce the room tail while making the voice sound less natural. The output may be cleaner without being better. The preview therefore has one job: let the listener switch quickly enough to hear both the improvement and the damage. The rule I use is deliberately boring. Both versions should contain the same edit and play from the same position. Switching should not restart playback or create a pause. The interface should not hint that one version is supposed to win. Two independent <audio> elements fail surprisingly quickly. Each owns its playback state, buffering behavior, clock, and seek operation. The user ends up finding the same position twice and comparing one sound with a memory of another. A better interface has one transport and one version control: [ Play ] [ Original | Processed ] 00:18 ━━━━━━━ 00:42 The transport decides where playback happens. The segmented control decides which signal is audible. One transport, two signals For a short preview, I decode both files into AudioBuffer s, start them at the same AudioContext time and offset, and route each through its own GainNode . Both sources run; only one gain is open. decodeAudioData() decodes complete file data and resamples it to the context's sample rate. The decoded buffers can then share the same audio clock. See the MDN documentation for format and loading details. The core is small: const context = new AudioContext (); const originalGain = context . createGain (); const processedGain = context . createGain (); originalGain . connect ( context . destination ); processedGain . connect ( context . destination )

Last year, Audi announced that it gave its all-EV-by-2033 plan the boot, and instead will offer a mix of gasoline, hybrid, and electrified propulsion. There's no doubt still some uncertainty among bigger automakers - especially those under the Volkswagen Group umbrella - when it comes to such a (now prior) commitment. Even so, what it's […]

Sennheiser announced the next version of its flagship wireless earbuds with a major redesign focusing on sustainability. The company claims the new design improves the Momentum True Wireless 5's "comfort, stability, and portability," but a more compelling reason to upgrade is that you won't have to replace them in a few years when they stop […]

We may have our first glimpse of Apple's rumored camera-equipped AirPods, thanks to a video that MacRumors found in the macOS Tahoe 26.7 Release Candidate. The short video clip features a man - who is wearing the new AirPods - holding up a book with the cover displayed, so that Visual Intelligence can see the […]

Sonos released an update to its mobile app that finally introduces support for iOS' Live Activities, giving iPhone users quick access to playback controls on their lockscreen. The added functionality is a "much requested, anticipated, and needed feature," according to a post Sonos shared to Reddit today that was spotted by 9to5Mac. While some features […]

Strings of code in Samsung's Galaxy Wearable app hint at an upcoming pair of over-ear headphones that could compete with the AirPods Max, SamMobile reports. Samsung's reportedly referring to the headphones as the "Galaxy H1," and SamMobile says they could launch sometime in 2027. That would make these the company's first pair of over-ear headphones […]

Today, I’m talking with Lila Snyder, who is the CEO of Bose. You certainly know Bose — it’s one of the most famous brands in all of consumer tech. The company started 60 years ago selling speakers to consumers, and its focus on research and development has led it to be a leader in both […]

Not every great pair of headphones belongs in the gym. These do, thanks to their secure fit, durable design, and impeccable sound.

Following the release of its premium and very expensive $650 The Collexion headphones in May, Sony could be taking its 1000X line of wireless noise-canceling headphones in a cheaper direction next month. The company is reportedly planning a refreshed and more affordable version of its six-year-old WH-1000XM4 headphones that will feature similar performance and specs […]
