### 5/5 — 감사합니다

*2026-07-10*

전에 몇 가지 건의를 부탁드렸는데 빠르게 반영해 주셔서 감사합니다. 현장에서 너무나 잘 쓰게 될 것 같습니다.

**Developer response:** 제가 감사합니다! 제가 전문 개발자가 아니어서 지금도 앱에 오류들이 눈에 보이는데, 빠르게 조치해서 업데이트 하겠습니다

### 5/5 — 건의

*2026-06-27*

레코딩 파일 사이즈 계산에 시간단위뿐만 아니라 분 단위 입력과 샘플레이트 44.1,88.2 등도 추가되면 좋겠네요.

거리 -> 시간 계산이 서로 반대도 되면 좋겠습니다.

거리 ->시간 계산할 때 온도 정도 옵션은 있으면 좋겠습니다 (습도까진 현장용이니 없다고 해도요.. 야외에서 쓸 수 있으니..)

SPL 더하기 계산도 있으면 좋을 듯합니다.

dBV, dBu, V 등 서로 변환하는 것도 있음 좋을 듯합니다.

앱 나갈 때 PIP 활성화하지 않는 설정 추가되면 좋겠습니다.

### 5/5 — 너무나 소중한 앱

*2026-06-11*

필요한것들만 꽉 차있네요. 
단위 변환할때 반대도 되면 더 좋을 것 같습니다.

**Developer response:** 감사합니다. 단위변환 반대 곧 적용해서 업데이트 하겠습니다!

음향 임플루언서 스토리 보구 구매했는데, 현장에서 쓰기 좋은 어플이네요

What's New

CALC — Completely Redesigned
• New home screen: all calculators organized into category cards — everything at a glance

• Distance–Delay: adjust temperature right inside the calculator
• Level Convert (dBu/dBV/V), dB Sum, and bidirectional inputs — now easier to find

Picture in Picture — Rebuilt
• Tap the PIP window for close and return-to-app controls

Plus stability and detail fixes throughout.

### 2.1.1 — 2026-07-08

What's New

SOUNDKIT is now free to download — one purchase unlocks everything.
Already bought the app? You get Pro for free. Thank you for the early support!

MEASURE
• True IEC 61672 A / C / Z frequency weighting for SPL
• Measurement-mode input — iOS auto-gain disabled for accurate readings
• Fine calibration with ±0.5 dB steppers
• Full Screen view: dB(A) & dB(C), Fast & Slow — all at once
• Picture-in-Picture: cleaner layout, kHz display, one-tap return

CALCULATE
• All-new CALC tab: 6 categories, 17 calculators
• Bidirectional inputs — enter either side (delay ⇄ distance)
• New: BPM delay times, note ⇄ frequency, comb filter, SPL over distance, amp power → SPL, dB sum, exposure limit, power load, dBu/dBV/V, impedance, latency
• Temperature-corrected speed of sound

FIXED
• Music from other apps no longer stops while using SOUNDKIT
• Auto-recovery after phone calls and mic/headphone changes
• Improved key detection accuracy

### 2.0.7 — 2026-06-10

Added a 32-bit option to the recording size calculator.

### 2.0.6 — 2026-06-09

What's New in 2.0.6

New
- Pinch-to-zoom on the RTA — spread two fingers to zoom into any part of the frequency axis (20 Hz–20 kHz), and double-tap to reset to full range.
- Tap-to-read frequency — touch and drag anywhere on the RTA graph to read the exact frequency in Hz at your fingertip.
- Clock in landscape — the current time now stays visible while you work in landscape.

Improvements
- Redesigned tempo entry — a large, easy-to-tap number pad replaces the small keyboard. In landscape it opens on the right half of the screen for comfortable typing.
- More accurate Key detection, especially for low and bass notes, with steadier readings that no longer flicker between keys.
- Steadier BPM readings that settle quickly and still react fast when the tempo changes.
- Better battery efficiency and smoother overall performance.
- Fresh new app icon.

Fixes
- Fixed text wrapping ("Searching…" / "STOP") on the SHOW screen in landscape.
