    I am wanting to execute a CLI command to convert all FLAC files to MP3, after looking on google and the usual places I have come up with procedure TForm1.act_MUSIC_CONVERSION_FLACStoMP3Execute(Sender: TObject); begin ShellExecute(0, nil, 'cmd.exe',PWideCHar( 'find '+PwideChar(form1.FileListBox1.Directory)+'. -name "*.flac" -exec ffmpeg -i {} -ab 320k -map_metadata 0 -id3v2_version 3 {}.mp3 \;'), nil, SW_HIDE); end; however the command window opens but nothing is executed :(

    Record and process audio

    lefjucabro posted a topic in Cross-platform

    Hello there, I am trying to develop an iOS app with Rio. This app must record audio and process it in real time to display some graphs. I am a newbie with FMX platform and iOS, there are lot of informations I don't get There is iOSapi.AVFoundation unit which contains a lot of types (TAVAudioSession, TAVAudioRecorder) but I cannot understand how to use them. For what I understand, I have to define an audio format (2 channels stereo, 16 bits), get the buffer size, create a recording task and then launch recording. In a thread I read samples and fill them into a TMemoryStream for processing. Do you think is this correct ? Do you have any idea how can I do this ? Kind regards Lefjucabro
