I was applying fx to my audio file on my ios app(using Xcode-swift app) and also from my mac (using terminal).
I need to create ROBOT effect (similar to transformer movie Transformer's voice). In Android, I was able to apply the FX using the following command: ffmpeg -i inputFile.m4a -af afftfilt="real='hypot(re,im)*sin(0)':imag='hypot(re,im)*cos(0)':win_size=512:overlap=0.75" outputFile.m4a But in iOS, it said, the win_size has to be between [4 - 17]. Hence I applied win_size=4. Then my command looks like: ffmpeg -i /Users/krishnarajs/Desktop/1/record.m4a -af afftfilt="real='hypot(re,im)*sin(0)':imag='hypot(re,im)*cos(0)':win_size=4:overlap=0.75" /Users/krishnarajs/Desktop/1/record1.m4a But while applying this filter, I'm getting following error: Unknown function in 're,im)*sin(0)' Failed to configure input pad on Parsed_afftfilt_0 Error reinitializing filters! Failed to inject frame into filter network: Invalid argument Error while processing the decoded data for stream #0:0 Am I doing anything wrong? Please help me. -- Krrish _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
