Audacity has released version 4.0, rebuilding its application interface on the Qt framework and introducing a redesigned clip-editing model. The update adds features like multi-clip selection and editing, clip grouping, freer clip placement across mono and stereo tracks, a dedicated splitting tool, smarter paste handling, and expanded snapping and alignment options.
A developer who struggled with traditional music instruction wrote a tutorial that builds music theory from scratch using code, starting with a single oscillating number representing air pressure. The piece shows how the twelve-note system, scales, and chords can be derived computationally from physics and arithmetic rather than memorized as arbitrary convention, using simple audio programming examples like sine wave oscillators.
Belkin's SoundForm Mini 2 wireless on-ear headphones, designed for children ages 3 and up, are currently discounted 25 percent using the code VERGE25OFF. The base model drops from $29.99 to $22.49, while the version with a zip-up carrying case falls from $39.99 to $29.99 after the code is applied.
A blog post from a former technical surveillance countermeasures practitioner examines a long-circulated claim from spy-hunting training: that fluorescent tubes can passively pick up room audio through subtle light fluctuations caused by sound waves. The author lays out the physical reasoning behind the theory, then flags reasons for skepticism, including the near-vacuum gas pressure inside tubes and the phosphor coating's afterglow properties, both of which would work against capturing sound accurately.
Sonos let journalists test its new Beam Ultra soundbar and Ace Ultra headphones in several setups, including standalone, paired with wireless Play speakers as surrounds, and streaming soundbar audio directly to the headphones. During a movie clip demo, the Beam Ultra delivered clear, well-balanced sound with surprising bass despite no subwoofer, while adding the Play speakers as rear surrounds noticeably improved immersion through Sonos's new Fabric technology, which lets devices sense their placement and surroundings.
Pixel 11 owners have reported static noise appearing in videos recorded using the Video Boost feature, which enhances color, lighting, stabilization and low-light detail. Google told Android Authority it has identified the cause and built a software fix that will roll out through the Camera app in the coming weeks, with further optimizations arriving in a future monthly Android update.
Dolby Atmos for Headphones is a paid app for Windows and Xbox that virtually recreates spatial audio effects on ordinary stereo headphones, without requiring dedicated Atmos-enabled hardware. Users can try the surround simulation through a free trial before deciding whether to purchase the full software.
Sonos has introduced the Ace Ultra, a premium successor to its Ace noise-canceling headphones priced at $449. The new model features Sonos-designed 40mm drivers, upgraded adaptive noise cancellation, a 10-microphone array, and Headphone Engine 2, which enables direct one-button linking to a user's Sonos system. Preorders open now, with shipping starting September 29 in black, soft white, agave and sand colorways.
A DIY enthusiast connected three existing security camera microphones to BirdNet-Go, an open-source, locally-run AI tool, to automatically identify bird species by song in real time. The system also picks up bats and frogs, runs entirely on local hardware without cloud services, and can send custom alerts—such as via Discord—when specific species are detected.
Google's latest Android 17 QPR2 Beta 4, released last Friday, makes it far easier to use a voice-broadcasting feature on Pixel phones that lets people speak or stream audio to nearby Bluetooth LE Audio devices, similar to a personal PA system. The capability, previously called Voicecast and buried in Developer Settings, can now be turned on instantly via a Quick Settings tile, provided Bluetooth is enabled, and supports password protection to block unwanted listeners.
After 18 months of development, the ReactOS project released version 0.4.16, introducing a graphical installer and merging the separate bootcd and livecd images into one unified disc. The update also brings improvements to video, audio, networking, and storage support, plus a new installation type and updated third-party code.
Apple's own guidelines reveal that lossless audio streaming through CarPlay only works over a wired USB connection, not wirelessly. This is because wired CarPlay uses the uncompressed LPCM codec, while wireless CarPlay relies on AAC-LC, a lossy codec that discards some original audio data to reduce file size.
