    Tutorial Time: making art in audacity and music in gimp

    Post  yellowninja on Thu Jul 31, 2014 4:33 pm

    Hello Friends! I have decided to make a tutorial on all this weird stuff I do so that you can do it too! This is all about being able to open images in audacity and music in gimp. I suggest starting with images in audacity because that's really easy to do and to make something good. Music is a lot harder and you will end up with abstract noise too often if you are not careful.

    Well first of all. you need to have Audacity and Gimp installed, so do that.

    Art in audacity:
    I'll start out by posting the videos where I learned how to do this.






    so, to do this, you need to convert your image into a .bmp (bitmap). I'm not really sure why  but that's the file type that works.

    open audacity and go to File>import>raw data

    Then choose your preferred photo. in the new window that pops up. choose (encoding) u-law,(byte-order) little-endian, and 1-channel (you can see all of this in the videos above)

    Now, you should have the picture as a sound file in audacity. now go to town and apply filters and whatever.

    NOTE: DO NOT TOUCH THE HEADER! The header  is the part of the file that tells the computer what the file is. Its at the very front and looks a tad different (see the top video for reference)


    NOTE: Make sure the total 'run time' doesn't change (if you delete a section, make sure to paste it somewhere else.) If the 'run time' changes, the image will not work/be view-able.

    when you are done: go to file>export click options and choose (Header) RAW, and (encoding) U-law. Then go to save as type and choose other uncompressed files and type .bmp at the end of your file name.




    Part 2: combining images:

    This is exactly the same as above. just choose 2 images that are EXACTLY THE SAME SIZE! Mute one of the headers and go to mix and render.

    Congratulations, You are done!

    Its worth noting that you picture will have a slight noise/ speckle to it. Its kind of unavoidable.




    Examples:
    these are images that I made. They are all 'fusions' of 2 images. The first 2 are a strait-up fusion and the last 2 have effects applied to them.

    Music in Gimp:

    Are you ready to be confused?


    Alright, First of all, remember everything from the previous tutorial because it all comes into play in this one in some form.

    I actually came up with this myself, so there is no video to go along with this tutorial.

    here is the song I was playing around with:



    first of all, we need to convert this music into an image. Remember that header from the previous tutorial? What we need to do is give the song an image header so that we can open it as an image.

    open the song in audacity

    choose a rather big/ high quality photo and convert it to .bmp (bitmap) and import it's raw data to audacity. we want a big photo because we need to cut the song to the same 'run time' as the photo and we want as much of the song as possible.

    but before we do that, we need the header of the image. zoom in and find the small bit at the beginning of the image that looks different from the rest and paste it to the beginning of the song

    then cut the end of the song as stated above.

    refrence:

    (copy and pasted header)











    (the top is the song and the bottom is the image I used)


    get rid of the image and export as stated in the previous tutorial.

    Now you can open the image in gimp and start editing. I am sure you can figure out the rest. Its hard to edit the music and still get something that sounds good. So, you need to be very careful and make changes that do not blur the image or distort it too much.


    examples of songs:

    because it take way to long to post videos to youtube, I am going to post the edited images and you can import them into audacity and listen to them that way

    these 2 were my favorites. But they didn't upload correctly as .bmp so I converted them to .jpg files. You can convert them back by opening them in gimp and saving as a .bmp

    selected a square and rotated by 90 deg

    painted over in yellow and selected 'hue' as the blending option

    Note: when making art, sometimes if your image is too big and it wont display properly in .bmp format. open them in gimp and save as a jpg. The same goes for audacity and the turning music into pictures.
