Even if it's a failed attempt. Introduction: 3D Printed Record. By amandaghassaei uh-man-duh-guss-eye-dot-com Follow. More by the author:. Here's a basic overview of my Processing algorithm: use raw audio data to set the groove depth - parse through the raw audio data, this is the set of numbers that defines the shape of the audio waveform, and use this information to set the height of the bottom of a spiral groove. In this video you can hear a periodic frequency sweep on top of the steady sine wave best heard w headphones.
This sweeping sound is caused by the needle moving over the thousands of tiny parallel bumps in the print caused by adjacent print-heads on the Objet machine. This noise is unavoidable, but increasing the strength of the signal will help to make it less noticeable.
Here is the video: RESULTS: At the end of all these tests I learned a few things about 3d printing records with the Objet: Groove Depth min of 48um below top of record - I found that grooves that kept the waveform at a minimum of 48um or 3 16 micron steps below the top of the record kept the needle in place while being played.
Attachments sine test 1. Processing has a library for dealing with audio called Minim , it is included with the more recent versions of Processing IDE.
Unfortunately, this library is set up for real time audio applications and does not appear give you an easy way of extracting all the data from an audio file at once it makes you load it in small buffers piece by piece. Since I could not find an easy way to load my wav files into Processing directly although I'm sure this must be possible , I've been importing stereo audio in the wav format into Python using the wav library, adding the left and right channels together, centering the data around zero, and exporting the resulting array of int's separated by commas to a txt file.
Here is my wav to txt Python script I'm running this in Python 2. Finally, it was time to start printing real audio! All my initial audio tests were done with the first 30 seconds from the opening track of one of the greatest albums ever written, The Pixies "Debaser. The code is heavily commented, but here's the overall gist: An audio file is basically a list of numbers that plot a waveform over time. The data that I pulled from Python in the last step is just that, the list of data points in the audio file.
Essentially what I did in this Processing sketch was use this data to set the depth of a long, spiral groove on the record's surface. Later when the needle passes over this groove, its tip will follow this path and actually trace out the original waveform stored in the audio data.
Here's what that sounds like: Signal to noise is getting better, I added a little more audio to this file so that you can start to hear Frank Black's vocals coming in. Here's the result of amplitude Signal to noise is better, but there is quite a bit of distortion. I decreased the amplitude to 24 next: This sounds a lot better. Good signal to noise without too much distortion. Next I made a slight edit to my code to minimize the amount of data packed into the stl file. In the previous examples I created some space between grooves, basically a flat surface parallel to the top of the record.
In the code below I removed this space and used the last upper edge of the previous groove as the upper edge of the next groove. The difference in the model is shown in fig 2. After nearly a week of printing, frantically running around downtown SF, and generally fighting with technology , I've got some reasonably good sounding audio to share with you: You'll notice that all of these prints are only about a minute long- this was due to some issues I was having with file size and RAM.

Deviation from this convention will lead to endianness issues, unless appropriate care is taken.
Hence, applications should manipulate such data 8-bits at a time, using 8-bit pointers. This violates the rule requiring surface data to be accessed in its true native format. As such, applications may be required to solve endianness issues. Possible solutions include:. Note: Complete details regarding each surface format's precise pixel layout is included with the documentation of each surface type.
Put another way, VDPAU implementations accept "slice" data from the bitstream, and perform all required processing of those slices e. VDPAU implementations must operate correctly if non-slice data is included, at least for formats employing start codes to delimit slice data. Include all slices beginning with start codes 0x through 0xAF. The slice start code must be included for all slices. The complete slice start code including 0x prefix must be included for all slices, even when the prefix is not included in the bitstream.
As such, no slice start codes should be included in the data passed to VDPAU; simply pass in the exact data from the bitstream. Header information contained in the bitstream should be parsed by the application and passed to VDPAU using the "picture info" data structure; this header information explicitly must not be included in the bitstream data passed to VDPAU for this encoding format.
Include all slices beginning with start codes 0xD frame , 0xC field or 0xB slice. The slice start code should be included in all cases. Some VC-1 advanced profile streams do not contain slice start codes; again, the container format must indicate where picture data begins and ends. In this case, pictures are assumed to be progressive and to contain a single slice.
It is highly recommended that applications detect this condition, and add the missing start codes to the bitstream passed to VDPAU. However, VDPAU implementations must allow bitstreams with missing start codes, and act as if a 0xD frame start code had been present. Note that pictures containing multiple slices, or interlace streams, must contain a complete set of slice start codes in the original bitstream; without them, it is not possible to correctly parse and decode the stream.
The bitstream passed to VDPAU should contain all original emulation prevention bytes present in the original bitstream; do not remove these from the bitstream. Include all slices beginning with start codes 0xB6. In addition to parsing and providing NAL units, an H. The complete slice start code including the 0x prefix must be included for all slices, even when the prefix is not included in the bitstream.
