Audio / Spectrum Analyzer reviews
4.6 out of 5, based on 5,940 reviews.
What people like
- Very simple and easy to use
- Helpful for testing audio systems
- Accurately shows signal frequencies
- Great for finding specific sound peaks
What they complain about
- No built-in recording or saving feature
- Drains battery if left running
- Crashes sometimes when you first open it
- Wave shape doesn't lock properly in real time
耳鳴り
耳鳴りの音に同期できる電子音を探していました。専門家ではないので何を触ったらどうなるとかはわからないけど色々触ってみています。同じ周波数なのに左耳と右耳では聞こえ方が違うということを発見しました。個人的には興味深いアプリだと思います。 バックグラウンドで聴けるようになると尚嬉しいです。
色反転バグが治んない
起動すると色が反転した状態で始まる。おまけにキーボードまで色反転されてる。自分のせいかもしれないけどこれ直して欲しいな
ピークホールド
ピークホールド機能を是非付けて下さい。出来ればホールド時間も選択出来ればなお有り難いです。 ピークホールドした画面にて、どの周波数のレベルが何dbなのか数値で分かる様カーソルを付けて下さい。
バックグラウンドで起動したままになるのやめてほしい
前まではなかったんですが最近になって手動でアプリを終了しないとずっと起動したままで気づかず10時間ぐらい動いてて充電がなくなってた
直感的で使いやすい
簡単な騒音計として使うには申し分ない。使い方もシンプルで分かりやすい。 今後さらに機能を改修されるようであれば ・A特性/C特性のフィルタを入れられると嬉しい ・デシベル表記の最小可聴音圧を20μPaに設定してもらえると、音圧の数字のスケールが見慣れたレベル感になるので変更できると尚よい ・波形をアウトプットできたら最高
とても面白い
とても面白い
もし可能であれば...!
もし可能であれば、オーディオインターフェースから入力された信号を見れるようにして欲しいです...!!
Good. Better if wave shape tracked.
Seems to function well with good refresh and analysis for simple use cases. But the wave shape only sits still at certain frequencies that happen to match the tracking speed of the display. I would pay for the app if it would track and lock the waveshape in place in real time, otherwise I can’t see complex wave shapes clearly.
Helped me fix the eq on my stereo
My sound system had a peak in the treble that I was able to get rid of by playing white noise through it and analyzing it using this app.
音を拾ってくれるけど
サンプリング周波数はどれぐらいなのかわからない
最高です！
素晴らしいです 他の方が書いているように録音機能があれば、更にいいですが、他の端末で録音すればいいので、この機能だけで非常にありがたいです！！
一点だけ追加機能が欲しい。。
機能はとても良いと思います！ ただ一点だけ、録音、保存機能が欲しいです。 1つのファイルは3分までとかで全然いいので。。 録音ファイル名も編集できると嬉しいです。 波形比較が出来ると、購入予定の楽器の音成分を 画像で可視化しながら 自分の体感と答え合わせができるので 非常に助かります。 それが入れば星5です！
正確な信号波形を出せない点以外はgood
440Hzで35Hzほど低い信号 1kHzでは785Hz低く表示される。 他のアプリで信号を出すとしっかり表示してくれます。信号発生を除けば満点です。
Bluetoothでノイズ
iPhone11ProMax、iOS 14.5.1ですが、Bluetoothでノイズをレシーバーに送れません。これが出来たらとても使い勝手が良いのですが。
Yup
Yup
バグ
なんか、最初起動する時、固まる。 それを直してくれたら、星5かな。 でも、アプリ自体は良い。 運営さん、早くアプデお願いします🙇
手軽で
しかも大変便利です。音に関わるいろんなことが発見できるようになりました。
Simple and useful frequency spread analyzer
This is a simple to use frequency analyzer that can be helpful for testing audio systems.
二点ほど希望
周波数の下にピアノがあれば耳コピに、かんたんに、使えるのに！ 今iphoneは48k固定なので、サンプリング周波数を対応してくれたら正確性が増すのに！
素晴らしい！
素人なので100%使いきれていませんがこの様なアプリが有って助かる！ 更にYouTuduで素人用に詳しい使い方やマイクロホン等の紹介、サイトで同様な使い方をプリント出来るように是非してほしい！ いずれFacebook に上げたいと思っています。
