Link Audio Bridge
Read full descriptionHide full description
Your iPhone, live in the session. Link Audio Bridge streams your iPhone's microphone, or any audio interface you plug in, straight into an Ableton Link session over your local network. It's metered, compressed and locked to the shared tempo. No cables to the computer and no account. STREAM โข Send mono or stereo audio to Ableton Live, or any Link peer that supports Link Audio, over Wi-Fi โข Pick any connected input: built-in mic, USB interface or headset โข Watch it the whole way with a stereo input meter on a true dB scale, with peak hold SHAPE โข A compressor built in, so the signal is under control before it leaves the phone โข Threshold, ratio, attack, release and make-up gain โข A live gain reduction meter shows exactly how hard it's working โข Your settings are remembered between sessions SYNC โข Locked to Link: shared tempo and beat position with every peer on the network โข Start and stop the Link transport from the phone โข A Link-synced click on the phone to play along to โข MIDI clock out, with start and stop, to keep other MIDI gear and apps in time WHAT YOU NEED โข Ableton Live 12.4 or later, or another compatible Link peer โข Your iPhone and computer on the same local network Something not working in your setup? Email hi@happyorbitlabs.com and tell us what you're running. The click only plays through the phone's own speaker or headphones and isn't sent into the stream, so the copy doesn't say it reaches Live.

LudyMeter measures sound levels with professional accuracy โ and does two things no other app can: track your noise exposure under EU workplace safety rules and detect musical notes from frequency peaks. No subscription. No ads. No data leaves your device. --- WHAT YOU GET FOR FREE --- The free tier is genuinely useful, not a teaser. You get a real-time A-weighted decibel meter with min, max, and average tracking. See how loud your environment is compared to everyday sounds ("As loud as a vacuum cleaner" or "Hearing damage risk after 2 hours"). Save your last 7 days of measurements and share beautiful sound level cards with friends. Works entirely offline. --- PRO ($14.99 one-time) --- Unlock the full frequency analyzer: real-time FFT spectrum, 1/1 and 1/3 octave band display, and musical note detection that translates raw frequencies into note names like A4, E3, or Bb2 โ with cent deviation. Compare before and after with A/B measurement snapshots. View spectrograms and get EQ recommendations for your room. Export unlimited measurement history to CSV. Supports A, C, and Z frequency weighting plus Fast, Slow, and Impulse time constants. Perfect for musicians, sound engineers, and audio enthusiasts who want a professional spectrum analyzer without a professional price tag. --- SAFETY ($49.99 one-time) --- The first and only iOS app with EU Directive 2003/10/EC noise exposure tracking. Calculate LEX,8h (daily noise exposure normalized to 8 hours), track LCpeak, and monitor your dose percentage in real time. A three-zone warning system turns green, amber, or red at the EU action values of 80, 85, and 87 dB(A). Get haptic alerts when you cross a threshold. Run full-shift background monitoring without keeping the screen on. Generate PDF screening reports with timestamps, location, and exposure status for workplace documentation. Also includes NIOSH and OSHA dosimeter modes for US workplace standards. Note: LudyMeter is a screening and awareness tool. It does not replace certified Class 1 or Class 2 sound level meters required for legally binding workplace noise assessments. --- WHY LUDYMETER --- PRIVACY FIRST Zero data collection. Zero analytics. Zero server calls. Your microphone audio is processed entirely on your iPhone and never recorded or transmitted. Works in airplane mode. App Store privacy label: Data Not Collected. BUILT FOR iOS 26 Designed from scratch with Liquid Glass, Dynamic Island, Live Activity, and home screen widgets. Dark mode optimized. 60fps animations driven by real audio input. TRANSPARENT CALIBRATION Three-tier calibration system: automatic per-device offset profiles, user single-point calibration against a reference, and external measurement microphone support with .cal file loading. We tell you exactly how accurate your readings are. ONE-TIME PURCHASE We believe utility apps should not charge monthly rent. Pay once for Pro or Safety, use forever. Free updates included. --- TECHNICAL SPECIFICATIONS --- - Frequency weighting: A, C, Z (flat) - Time weighting: Fast (125ms), Slow (1s), Impulse (35ms rise / 1500ms decay) - FFT: 4096-point Hann window, 50% overlap, 20 Hz update rate - Octave bands: 1/1 (10 bands) and 1/3 (33 bands), IEC 61260-1 centers - Pitch detection: YIN algorithm, +/-0.5 cent accuracy - Audio engine: AVAudioEngine in .measurement mode (no AGC, no noise suppression) - EU thresholds: 80/85/87 dB(A) LEX,8h, 135/137/140 dB(C) LCpeak - US standards: NIOSH REL (85 dBA/8h, 3dB exchange), OSHA PEL (90 dBA/8h, 5dB exchange) - Minimum device: iPhone with iOS 17+ - Designed for: iOS 26 Liquid Glass From the makers of Ludy apps.
