[HELP] how to export WAV file to AAC in Hybrid?

[ssdde]

if there is a wav file, i want to using Hybrid to export it a AAC file,

i try to use this way below, but the area "Base->output file" only must can be video format, i only want a AAC file, so how to?

• Set "Base->Processing->Audio" to "Custom"
  
  
• Select the external audio stream under "Audio->Base->Audio Source->Audio File"
  
  
• If you want that Hybrid should reencode the audio you need to enable 'Audio->Base->Audio Encoding Options' and set the encoding and filtering options. If you do not want Hybrid to reencode the audio, make sure 'Audio->Base->Audio Encoding Options' is disabled.
  
  
• Once the settings are as you want add the settings to the 'Audio Queue' (press 'Audio->Base->Add current')
