## What is Analyzer?

The Analyzer is a combination of a sound pressure level (SPL) meter and a full range multiple bands frequency analyzer. It is mainly designed for audio professionals who need to evaluate different working environments (e.g. studios, live stages)... that’s why it’s perfect for anyone who’s in need of acoustical analysis!! It is easy to use and comes with amazing features only known from professional acoustic tools.

Use the Analyzer for measuring stages, testing speakers, setting up your hi-fi system, evaluating sound mixing environments, analyzing your instrument... or for measuring the noise your neighbor makes with his new stereo!

The Analyzer is pre-calibrated for all iDevices, but it includes a calibration function as well. It comes with a highly intuitive user interface with zoom gesture control, individual color settings, reticle zoom and many more exciting features. The Analyzer can store, load and export measurement data and supports iCloud storage.

Combine the Analyzer with external microphones such as the MicW i436 or Microtech M372 for better measurement performance! Or use it with external USB audio hardware like the RME Fireface UCX or the Alesis IO dock, change the measurement scale to dB (FS) and use it as a studio Realtime Analyzer!

### 5/5 — erstklassig

*2026-01-17*

Nutze diese App schon seit sehr vielen Jahren. Wenn man sich nur ein ganz kleines bisschen einliest dann kann jeder ziemlich professionell einen Frequenzgang erstellen, im eigenen Raum, das ist viel mehr wert als irgendwelche Frequenzgänge in irgendwelchen Zeitschriften. Langer Rede kurzer Sinn: diese App ist erstklassig

### 1/5 — I can’t see the frequencies. Too small!!!

*2025-02-06, version 3.2.1*

The frequency call outs are microscopic!!!   It’s horrible!!! I can’t read it. Waste of money

### 3/5 — Love the app but….

*2024-04-27, version 3.2.1*

I used to use this exclusively for my music system since I love the features, but it won’t load as an IAA in Aum or Audiobus anymore…. so I only use it as a stand alone app, which is unfortunately rarely.

### 1/5 — Проблема iPhone xr!!!

*2020-09-11*

Не обновляйтесь! Экран растянули и теперь не весь частотный диапазон возможно увидеть!!!

### 5/5 — Funktioniert wieder!

*2020-09-04*

Netter Kontakt mit den Support, mit dem aktuellen Update läuft es wieder mit dem aktuellen IOs.

### 5/5 — Aktuell Fehler -214 dB

*2020-07-24*

Geht aktuell nicht Update nötig

Fehler behoben funktioniert wieder , top

**Developer response:** Bitte beim Neustart Leq ausschalten, das sollte das Problem beheben. Sie können sich auch gern an support@dspmobile.com wenden!

### 1/5 — Не работает

*2020-07-24*

После обновления перестала работать программа на iPhone 6 plus, iOS 12.4.7. Верните деньги!

### 5/5 — Schneller Support - Danke

*2020-07-24*

Nach dem Update auf IOS 13.6 funktionierte die App nicht mehr korrekt. Super schnelle Information auf Nachfrage per Mail. Und schnelle Reaktion und Patch. Toll Danke . 
Ich bin wieder sehr zufrieden.

### 5/5 — Still going strong, years later

*2020-07-20, version 3.0*

I use this app all the time for ringing out microphones, measuring SPL at concerts and in my car, with home theater setups, tuning subwoofer boxes, calculating the idle on my motorcycle... I could go on.
There was recently an update that caused the app to crash on my 5s running 12.4.8. I emailed the devs and received back a notification of a fix and scheduled update within minutes. And so I am here to write a review. 

The best part of this app that I haven’t seen other apps do is the ability to save snapshots of frequency spectrum, to adjust the window function width, and simultaneously output different noise while capturing the input response. Super handy.

This app and service are worth every penny and should have higher reviews. Low reviewers don’t know what this app does or how to use it.

### 3/5 — Update 3.0 läuft nicht auf iPhone SE?

*2020-07-10*

Hallo, habe das Update auf 3.0 angewendet ( iPhone SE, neuestes iOS) - leider funzt die App nicht mehr?!
Ist das Thema schon gelöst?

**Developer response:** Fehler gefunden- update kommt demnächst!
