Note: SignalScope has been replaced by the new SignalScope X and will no longer be updated. You will be able to continue to use SignalScope as long as you run it on a device with a compatible version of iOS. SignalScope X offers powerful new tools and features. You can download it for free and try out the Pro features for free for up to 7 days. SignalScope turns your iOS device into a powerful real-time spectrum analyzer and oscilloscope. Easily measure audible frequencies in SignalScope’s FFT analyzer. See for video demos. For more information regarding compatible audio hardware, visit Features: - Analyze signals coming from the iOS device’s current audio input source, or from the built-in accelerometer. - Assign input channel units and sensitivities for individual USB Audio devices. Direct support is included for the Digiducer 333D01 accelerometer and miniDSP UMIK-1 measurement microphone. - Manually switch between available audio input sources. - Load microphone frequency response data (FRD) and apply frequency response correction (FRC) to FFT spectrum measurements. - Audio input is typically sampled at 48 kHz or 44.1 kHz (higher and lower sample rates are possible, even up to 192 kHz, with hardware that supports it). Built-in accelerometer data is sampled at roughly 100 Hz. - Zoom in or out on spectrum and waveform displays with two-finger expand/pinch gestures, even while the analyzer is running. - Pan vertically or horizontally in zoomed displays with two-finger scrolling. - Pinpoint individual sample values or frequencies with a cursor. - Save high-resolution spectrum or waveform display images as PDF files or as JPEG images in the iPhone's Camera Roll photo album. SignalScope supports full and partial upgrades to the additional tools and functionality offered in SignalScope Pro. Upgrades may be purchased via in-app purchase. Available in-app purchase upgrades include: - Upgrade to the functionality of SignalScope Pro. - Signal Generator tool (not the same as SignalSuite). - - Random and periodic pseudorandom noise (period defined by FFT length) - - White and pink noise weighting - - Lin and log frequency sweeps - - Tone generator - Octave and 1/3-octave Analyzer tool (RTA). - - Whole and 1/3-octave RTA (based on digital Butterworth bandpass filters)Fast, Slow, and Impulse response times - - Flat, A, and C frequency weighting - - Equivalent and time-weighted exponential average levels - - Max, peak, and elapsed time also captured - Level Meter tool. - - Flat, A, and C frequency weighting - - Equivalent and time-weighted exponential average levels - - Max, peak, and elapsed time also captured - Real-time Spectrogram Analyzer (available in 2D and 3D versions) -- Frequency resolutions between 1 and 50 Hz may be specified for audio input (between 1 Hz and 10 Hz for the built-in accelerometer) -- Input data can be windowed with one of 7 different data window types -- Lin, log, and dB magnitude scales -- Lin and log frequency scales -- Fractional-octave band frequency smoothing in 1/6, 1/12, and 1/24-octave bands. -- Cursor peak track can track peaks in time, frequency, or both. -- Color scale bar graph enables manual adjustment of magnitude scale and offset. The color scale can also be hidden. -- Data may be exported to CVS, MAT, or TXT files for post processing or plotting. Optionally, include GPS location information with exported data (Data Acquisition Upgrade required). -- Optionally save a high-resolution PDF file of the spectrogram plot, or save an image to your Photos library. - Data acquisition (CSV, TXT and MAT file data capture) with downloading to Mac or PC via a standard web browser or iTunes File Sharing. Includes support for additional engineering units (V, A, m/s^2, m/s, g, ips), which are assignable to audio input channels.



  • 素晴らしいアプリです

    大変お世話になっているアプリです。出先での手軽な音響解析などに使っています。 3,000円近い値段がしますが、決して高い値段ではないと思います。

    仕事で使えそうです。 今後の期待を込めて星4で。 下記は気付いた点です。 アップデートでSigGenを入れたら毎回レストアしないと復旧しなくなる不具合は解消されました。プロを買えば良かったと後悔しかけましたが、安心しました。他の機能も追加しようかなと考えています。 プロットのセーブはカメラロールに保存されるjpegをオススメします。私が発見出来ていないだけなのかもしれませんが、pdfが保存されているディレクトリにアクセス出来ません。 結局、フリーソフトでMacから直接アクセスして閲覧、削除しました。あまりクオリティの高いpdfファイルでもありませんでしたし。
  • 結構使えます。

    PAの現場で補助的に使っています。 反応も良いし何しろiPhoneのこのサイズですから歩き回るのに便利です。
  • まずまず使えるみたい^^

    ちょっと高いと思いましたが、思い切ってDLしました。多少起動が不安定な場合がありますが、動き出せば結構使えるようです。 内臓マイク単独で使えますし、ヘッドセットのマイクからも使えるようです。レスポンスもすばやいです。 PAスピーカーのチューニングの補助に現場で使ってみようと思います。
