LM2n and LM6n are almost identical. Both plug-ins give you super-accurate loudness measuring, normal and big radar views, faster-than-realtime AudioSuite measuring in Pro Tools and much more. Only two things set them apart:
- LM2n Supports Mono and Stereo - LM6n Supports Mono, Stereo and 5.1 Surround
- LM6n Includes Logging of Loudness Stats. LM2n Does Not
So, if you need to work with 5.1 surround or need to log your loudness stats, LM6n is your best choice.
