Ratings and Reviews
Crashes when creating a new audio recording
Really promising app, unfortunately it crashes when you try to create a new audio recording from the menu. A fix would be greatly appreciated for a $9 app!
Developer Response ,
Thank you for reporting it and I am sorry for encountering this. This issue is fixed in version 1.5.
Can’t open pre-recorded files
Wasn’t clear from the description (since it said "import from any source") but the app won’t import a pre-recorded file. There is no help file, nor documentation. Tried .wav, mp3, and m4p without luck.
Developer Response ,
It does support wav files in recent versions. The description was not as clear as it should have been.
Bull crap
Nothing but a file folder ap doesn’t work at all should get my money back do not buy
Developer Response ,
Signal Path is a file based app for recording and reading data from files. New recordings can be created by tapping on the + button in the file selection/creation view.
