What's New in Tuner T1

4.30

October 30, 2026

This update brings powerful new audio input options, improved noise filtering, and significant performance enhancements for a smoother, more reliable tuning experience. Select Any Audio Input Channel Using an external audio interface? You can now choose exactly which input channel Tuner T1 listens to! Connect a compatible multi-channel audio interface and select your preferred channel directly within the app. Whether you're recording in a studio, connecting instruments through an audio interface, or working with a professional audio setup, you now have greater control over your tuning input. New Lo Cut Filter - Cleaner Tuning in Noisy Environments Introducing Lo Cut, a new audio filtering option that lets you filter out frequencies below a selected threshold. Low-frequency rumble from air conditioners, traffic, stage vibrations, and other environmental noise can interfere with pitch detection. With Lo Cut, you can reduce these unwanted frequencies, helping Tuner T1 focus on your instrument's sound for more stable and accurate tuning. Especially useful for live performances, rehearsal spaces, and noisy environments. For bass guitars and other low-pitched instruments, choose a lower cutoff to preserve the fundamental frequencies you need to tune. Significantly Improved Performance We've made major under-the-hood optimizations to make Tuner T1 faster, smoother, and more responsive. From real-time pitch detection to on-screen animations and general navigation, everything feels more fluid and polished. Enjoy a better tuning experience, whether you're practicing at home, performing on stage, or working in the studio. Thank you for using Tuner T1! Your feedback helps us keep making it better.
