Hello, @Sergelenchimeg @dikshit1400 if possible can you please provide more information or block of code because i have tested in IOS 18 and it's working well. Thank you

I have been facing the same issue in iOS , here is the base code.

void _initializeControllers() { recorderController = RecorderController() ..androidEncoder = AndroidEncoder.aac ..androidOutputFormat = AndroidOutputFormat.mpeg4 ..iosEncoder = IosEncoder.kAudioFormatMPEG4AAC ..sampleRate = 44100; }

await playerController .preparePlayer( path: path!, noOfSamples: 100, volume: 1.0, shouldExtractWaveform: true) .catchError((e) { printDebug(e.toString()); }); await playerController.startPlayer( finishMode: FinishMode.loop); },

Error: flutter: PlatformException(AudioWaveforms, Failed to prepare player, The operation couldn’t be completed. (OSStatus error 2003334207.), null)
