"""Stuff to parse Sun and NeXT audio files.
An audio file consists of a header followed by the data. The structure
of the header is as follows.
+---------------+
| magic word |
+---------------+
| header size |
+---------------+
| data size |
+---------------+
| encoding |
+---------------+
| sample rate |
+---------------+
| # of channels |
+---------------+
| info |
| |
+---------------+
The magic word consists of the 4 characters '.snd'. Apart from the
info field, all header fields are 4 bytes in size. They are all
32-bit unsigned integers encoded in big-endian byte order.
The header size really gives the start of the data.
The data size is the physical size of the data. From the other
parameters the number of frames can be calculated.
The encoding gives the way in which audio samples are encoded.
Possible values are listed below.
The info field currently consists of an ASCII string giving a
human-readable description of the audio file. The info field is
padded with NUL bytes to the header size.
Usage.
Reading audio files:
f = sunau.open(file, 'r')
where file is either the name of a file or an open file pointer.
The open file pointer must have methods read(), seek(), and close().
When the setpos() and rewind() methods are not used, the seek()
method is not necessary.
This returns an instance of a class with the following public methods:
getnchannels() -- returns number of audio channels (1 for
mono, 2 for stereo)
getsampwidth() -- returns sample width in bytes
getframerate() -- returns sampling frequency
getnframes() -- returns number of audio frames
getcomptype() -- returns compression type ('NONE' or 'ULAW')
getcompname() -- returns human-readable version of
compression type ('not compressed' matches 'NONE')
getparams() -- returns a namedtuple consisting of all of the
above in the above order
getmarkers() -- returns None (for compatibility with the
aifc module)
getmark(id) -- raises an error since the mark does not
exist (for compatibility with the aifc module)
readframes(n) -- returns at most n frames of audio
rewind() -- rewind to the beginning of the audio stream
setpos(pos) -- seek to the specified position
tell() -- return the current position
close() -- close the instance (make it unusable)
The position returned by tell() and the position given to setpos()
are compatible and have nothing to do with the actual position in the
file.
The close() method is called automatically when the class instance
is destroyed.
Writing audio files:
f = sunau.open(file, 'w')
where file is either the name of a file or an open file pointer.
The open file pointer must have methods write(), tell(), seek(), and
close().
This returns an instance of a class with the following public methods:
setnchannels(n) -- set the number of channels
setsampwidth(n) -- set the sample width
setframerate(n) -- set the frame rate
setnframes(n) -- set the number of frames
setcomptype(type, name)
-- set the compression type and the
human-readable compression type
setparams(tuple)-- set all parameters at once
tell() -- return current position in output file
writeframesraw(data)
-- write audio frames without pathing up the
file header
writeframes(data)
-- write audio frames and patch up the file header
close() -- patch up the file header and close the
output file
You should set the parameters before the first writeframesraw or
writeframes. The total number of frames does not need to be set,
but when it is set to the correct value, the header does not have to
be patched up.
It is best to first set all parameters, perhaps possibly the
compression type, and then write audio frames using writeframesraw.
When all frames have been written, either call writeframes(b'') or
close() to patch up the sizes in the header.
The close() method is called automatically when the class instance
is destroyed.

I am a small town Minnesota single mom of two great kids who are my life. I began modeling 3 years ago for a photographer ho saw something in me I never did. Ice told me I should do one shoot with him and let that be the guide. I reluctantly agreed, and scheduled our date. I was sacred to death when he told me we would be doing a remake of the publicity stills of the 1956 movie Bus Stop, staring Marilyn Monroe. How in the world could I halfway resemble or pull off an icon the likes of Marylin Monroe in my first step in front of camera? Well, 2 hours later we had a nice set of images and I've been hooked ever since. We've done some really cool things and are looking hard at the future ahead to expand and get me out there a little more.
My pinup journey started at the age of 13 when I started collecting vintage decor and clothing- it has since spiraled into doing pinup shoots, meeting and developing friendships with other gorgeous pinups and being published in a pinup blog and magazine. Looking forward to the future and to see where other opportunities will take me!

I started getting into collecting vintage when I was a young kid, my mom would always take me into antique stores and this seemed to be what fueled it all. Eventually I started dressing and collecting vintage clothing and home decor. My apartment is now a great mix of MCM. I’ve done several pinup photoshoots and am looking to doing more in the future. I have been featured in a online pinup blog as well as being published in an state content creators magazine. Looking forward to the future and all the adventures it brings going forward.

My awesome journey began in California, followed by 25 wonderful years in Colorado. In 2019 I made the best choice of my life—moving to Florida, where I’ve truly found my home. The pin up community has been amazing, as I have always been drawn to the vibrant world of rockabilly style, classic cars, and music. Known for being kind, generous, and full of adventure, I cherish my experiences and connecting with new people. As a proud member of "Pinups and Pumps," I deeply appreciate the camaraderie with my sisters. Together, we give back through charity events, creating lasting bonds and memories.

Clarice entered the pinup scene officially in 2019. Her first photoshoot was a tribute to the queen herself, Bettie Page. Dawning the same iconic bangs and hair darker than the devil's soul, she was a tattooed dead ringer. That photoshoot was featured in Retro Lovely's Bettie Page issue in 2019.
6 years later Clarice is a style of her own, finding herself more and more every day. She's a mental health advocate, constantly trying to educate about mental illness to help end the stigma. In March of this year she'll be celebrating 3 years free from alcohol. Supporting sobriety amongst her community is also a passion. Clarice is also Autistic, and tries to educate on hidden disabilities. Not only is she a pinup, she's a mommy first. Having 3 biological children, 3 "step"children, and her youngest being adopted, who's also autistic.
She enjoys creating art through painting, drawing, photography, and floral hair pieces.
Find her at the car shows, especially if there are rat rods and lowriders involved. Lowriders have been a part of her heart since high school. From being in a friend's hopper getting Taco Bell past her curfew, or cruising the beach with the systems bumping.
The name Clarice Von Darling is a tribute to The Silence of the Lambs. In her sister's memory.
62 year old trans woman who is now retired and living life to the fullest.
