{"appstoreID":1210488485,"title":"Signal Path","subtitle":"Record and view spectrums","developerName":"Toomas Vahter","description":"Signal Path is the most performant spectrum viewing app with beautiful user interface. You can record audio spectrums using microphone and replay them or open large recordings containing I/Q data.\n\nInspect spectrums\nSpectrums can be selected using two finger drag gesture. Tapping on histogram reveals amplitude value of the selected frequency bin.\n\nAdjust thresholds\nSignal Path automatically expands amplitude threshold range when viewing spectrums. You can also set custom amplitude thresholds if needed.\n\nKeeping file size under control\nSignal Path can set a maximum file size for recording after which file is recreated.\n\nCan open wav files and save recorded audio as wav\n\nSupported interleaved raw I/Q data formats\nFloat, int8, int16, int32, uInt8, uInt16, and uInt32\n\nFast Fourier transform lengths\n256, 512, 1024, 2048, 4096, 8192\n\nWindow functions\nRectangular, Blackman, Hamming, and Hann","bundleID":"com.augmentedcode.SignalPath","appiconURL":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/3f/39/4d/3f394d79-17bb-e441-2ce2-6c700ca57033/Placeholder.mill/1024x1024w.webp","formattedPrice":"$8.99","appUpdated":"2026-09-17T22:35:52.000Z","appReleased":"2017-03-06T23:05:22.000Z","version":"2.10","platforms":["mac","iphone","ipad"],"minOS":{"iphone":"Requires iOS 26.6 or later.","ipad":"Requires iPadOS 26.6 or later.","mac":"Requires macOS 26.6 or later.","vision":"Requires visionOS 26.6 or later."},"topIAPs":[],"languages":["EN"],"size":"4 MB","category":"Music","developerWebsite":"https://augmentedcode.io/portfolio/signalpath/","screenshots":[{"platform":"ipad","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/0b/77/c6/0b77c69d-9b5b-0715-e0f9-c37739bc6685/9b2566c2-c662-40a7-a98c-18fb786b7afd_iPad_Pro__U002812.9-inch_U0029__U00283rd_generation_U0029-1-SpectrogramSelection_framed.png/2048x2732w.webp"},{"platform":"ipad","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/ea/d5/26/ead5264b-1d36-e5dc-8789-06ac16f2e792/a0aab537-a2ec-4e2a-99f5-eb1d5478f15f_iPad_Pro__U002812.9-inch_U0029__U00283rd_generation_U0029-2-HistogramSelection_framed.png/2048x2732w.webp"},{"platform":"ipad","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/2f/4a/8e/2f4a8ecf-8acf-8edb-cf06-ef120f902225/c7eadd74-da84-4535-9177-4d91a67e30b6_iPad_Pro__U002812.9-inch_U0029__U00283rd_generation_U0029-3-AudioRecording_framed.png/2048x2732w.webp"},{"platform":"ipad","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/d6/f8/80/d6f88053-1b0d-f55e-dc30-a008ed4f4d0a/f464aedd-dfcf-4f8e-af10-92aa2b38d2bb_iPad_Pro__U002812.9-inch_U0029__U00283rd_generation_U0029-4-FFTSettings_framed.png/2048x2732w.webp"},{"platform":"ipad","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/be/86/97/be86971f-c381-b331-94a6-2fcd79a3f32f/b4853fdd-b54a-499a-96b6-eecb642f8417_iPad_Pro__U002812.9-inch_U0029__U00283rd_generation_U0029-5-HeatMapSettings_framed.png/2048x2732w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/74/fa/fb/74fafb6d-b1a1-9250-5ce1-c7cb18501108/4b7c384d-0601-4d81-8e70-7c197a67e825_iPhone_11_Pro-1-SpectrogramSelection_framed.png/1125x2436w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/7e/35/58/7e355801-bc7a-51cf-8493-af85a94847f1/8f9a0152-50ef-4479-8a52-aebb3aae3b41_iPhone_11_Pro-2-HistogramSelection_framed.png/1125x2436w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/7f/8a/cd/7f8acd16-2927-3feb-c8aa-e7de6465713e/abb1c761-8823-4dd2-8a6e-2539f712cb04_iPhone_11_Pro-3-AudioRecording_framed.png/1125x2436w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/ee/a3/60/eea360ac-5e46-2612-c879-468d085c66fc/45bf1d40-8c78-43a2-aab6-3770e9080485_iPhone_11_Pro-4-FFTSettings_framed.png/1125x2436w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/4c/f6/f0/4cf6f038-a512-cb05-ae04-42f903a885e3/4c80a52c-858c-4698-8103-922d87253f95_iPhone_11_Pro-5-HeatMapSettings_framed.png/1125x2436w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/Purple114/v4/11/d5/2e/11d52e62-a8d8-6a76-2a69-9549a5b2eabb/89b6772c-18c2-4ffa-921a-fc0f627180c3_iTunes1.png/1440x900w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/Purple114/v4/7a/35/23/7a352344-ce07-ad31-6166-8e32d7753fbe/6340a741-9277-4c71-a582-ddc513c46790_iTunes2.png/1440x900w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/Purple124/v4/cb/ea/10/cbea10de-ee37-762d-3e81-bbafa634bcfc/518e9676-b079-4603-a554-6584dbcc5382_iTunes3.png/1440x900w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/Purple114/v4/33/9c/12/339c122b-a230-222d-d46c-c3a7c402210b/0226c0c7-f31b-40dd-ba69-c55c77532a76_iTunes4.png/1440x900w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/03/76/fa/0376fa48-f9aa-9662-a016-b3459ac29e04/556ee61d-8ce0-438f-bd4d-5c64482493df_iTunes_5.png/1440x900w.webp"}]}
