Hello,

thank you for making the distribution HifiberryOS. I like to use it with some room compensation using REW. Unfortunately isn´t it possible to transfer these files (left and right speaker are separeted). I wanted to put my own correction data (like written in your documentation about room equalisation), but after (successfull) login it is not possible to write commands: Every line begins with a "#". Can you tell me how i can write my data and commands over putty?

Thank you in advice,

Tobias

  i assume you use Dac+Dsp card:

  first create your separate L&R filters in rew:

  https://www.hifiberry.com/docs/software/implementing-room-acoustics-correction-using-rew/

  send to pi with scp:

  scp filter-L.txt root@192.168.1.82:

  scp filter-R.txt root@192.168.1.82:

  connect to pi

  ssh root@192.168.1.82

  apply filters:

  dsptoolkit apply-rew-filters-left filter-L.txt

  dsptoolkit apply-rew-filters-right filter-R.txt

  Hello Domenico,

   

  thank you very much for your answer. This is exactly the way I want to do it, but putty won´t let me. The Login procedure is working normaly. But afterwards every line begins with a "#", so no command will be accepted. Here you can see it on a screenshot:

  

  Best Regards,

  Tobias

  Hello Domenico,

  you have right, I can apply the specific commands normaly. I was just confused that I can not perform other commands. Thank you and have a nice weekend!
