User reviews

L K

Works well for me to test the crossover frequency for my sub. iOS 26.5 iPhone pro 15. Thanks for not charging subscription.

Does not work in iOS 18

Since updating to iOS 18 this app opens but I can’t start a measurement. There is no input read on the mic.

ATGとの同時使用に関して

車のスピーカー特性のチューニングに本アプリとATGを購入したが、ATGのホワイトノイズをBluetooth経由で再生しながら本アプリを立ち上げるとATGの再生が停止してしまう。
せっかく同じ会社で開発されているので同時使用できるように改善して欲しい。

Great tool

This a great tool that just plain works and is reliable. Been using itfor years! Really helps ringing out monitors on stage.

単純明解なアナライザーです。

単純明解なんですが、表示レンジが全て「ー」表示になるんで、0dBを任意の数値に変更出来て、1コマ10dBを5dBとか任意の値にコントロール出来れば、星5ツでした。(もう少し細かく見たいです)
後、欲を言うなら、SLOWにするとカクカク動くので、もう少しなんとかなればと、平均化する事が出来れば100点でした。
全帯域でマイクのキャリブレーションが出来るのは、とても良い機能なんですが…。このアプリだけでキャリブレーションするのは、ちょっとシンドイです。
それと、大きな信号が入ると内蔵マイクに切り替わるらしいのですが、何のマイクを受けているのか?!分からない事と、動いていて触らないでいると、画面がスリープになるのもなんとかなりませんかネ?!
バージョンアップに大きく期待して、ちょっと辛口意見でした。
