Virtual Audio Driver For Windows (XP, Vista, Win7) (repost)

Write a Virtual Audio Driver for Windows (addressed as VAD below). Must work under:

o Windows XP
o Windows Vista x32 AND x64
o Windows 7 x32 AND x64

The driver must appear as a normal Audio Output Device to Windows and any application. The
device must appear in Windows control panel – sound management and we should have the possibility to set it as default audio device. For Windows and any other application VAD should look like a real hardware driver and act like one.

Upon installation it should remember the previous default audio output device, and as its default behaviour should route all its input sound to the previous default audio device. It should notice if this device disappears or is replaced (for instance the computer gets a new audio card) and remember this incident(always just the last incident, not a history).

Basically VAD should get the input from an application and pass it directly to the former primary audio driver. This should happen with a minimum of strain on the CPU. VAD should be aware of what process is sending witch stream.

The VAD should have some API calls that can be addressed from other programs. The main call should be the possibility of hooking into the audio stream of a another program. Api calls should be protected by some sort of password mechanism, meaning that only applications that know that password or protection should be able to hook on the audio stream. Hooking on the audio stream means that the program gets to listen on the output of any given process but the stream flows further to the former primary audio driver too.

Source Code must be documented and Api calls will be documented by us upon accepting your bid.
Please do not bid for a DIRECT SHOW filter or similar solutions. We need this to be a proper System driver working in all those environments (keep in mind also 64 bit!)


Project will be executed as an Audio Filter Driver.
This Driver will be installable on Win XP32, Vista 32/64, Windows 7 32/64.

It will have the functionality described in the initial project, without the Hardware device tracking described.

It will allow to identify the stream source process.

It will implement the following API calls that can be called from a third party application (this is a part where we can be flexible, your input or suggestions are welcomed) :

int VAD_HookStream(*char passcode,int processid, *streamReaderFunc callback_func)

Hooks all streams from the process processid and feeds the data to the callback function callback_func
If processid is 0 then ALL the audio data is feeded to the callback function

Returns a handler

int VAD_UnHookStream (handler int)

Unhooks a previous callback related to that handle.
retuns -1 if handle was not found, 1 if successfull, 0 if error

int VAD_InfoStreams (*char passcode, stream_info* streamStruct)

Gets the information about current streams that flow through the VAD at that point.
stream_info is a dynamic array of structures in form of a pointer list; Return value is the number of stream_info structures;

struct stream_info
int processid; //process id
int starttime; // time stamp when the stream started
int bytecount; //how many bytes were streamed until now
[here we could add 2-3 other info variables. ]
*stream_info next_info; //pointer to the next infomation block. null pointer if its the //last

Stream Audio From Axis IP Camera To Android And Iphone

Axis IP cameras are using VAPIX (open API) to transfer remotelly audio from camera mic over http, and to send audio over http to the integrated camera speaker. The audio is raw stream, encoded with G711 (mulaw encoding).

We need a simple code (library, codec, or utility class with few methods) which will play the streamed audio remotely from the camera mic on Android and iPhone devices; and vice-versa (to send audio from the android/iPhone microphone to Axis camera speaker, over VAPIX API.

The audio must be clear with correct encoding/ no white noise.

It is preferable to apply, if you have already experience with VAPIX and deal with this / similar problem before.

Seeking singer for 15 short songs.

15 short songs (average :20 seconds each.)

You will be responsible for singing:
3 part harmony and 1 short lead part).

Technical note:
1. You must have access to a professional microphone and software (or recording studio) in which to record the vocals. Looking for the highest quality audio output possible. No 16 bit audio tracks.

2. I will provide separate tracks that are "guide/rough tracks" where the parts are sung for you.

3. You must be able to sing in English Language. Accent is not a problem, but if your lyrics/singing is not intelligible to an English speaker/fan, that will not work. So your accent would be fine (if you are an English as a second language speaker) but your lyrics must be clear and precise.

4. You wont have to clean noise from you vocal tracks that will be done on my end.

SUBMISSION: Please include link to sample of you singing. I would prefer hearing your singing without the addition of effects. I will not consider tracks that include auto-tune. Tracks as simple as you singing to a guitar or keyboard accompaniment would be awesome as Id be able to better determine whether your have great vocals or a great studio/engineer.

The completed songs will be used for several album projects Im working on. Youll get textual credit in the album and music videos.

I retain all my copyrights and publishing rights to the songs. This will be considered a "work for hire".

CutterBox Audio

I am preparing a project for a Kickstarter campaign that involves audio, bluetooth etc. for Ipods and Iphones. Ill be paying for the design services myself though. Im looking to get a product design to put into the movie intro for the product. So renderings are really only thats necessary. Ill repost another project for product manufacturing and so forth after I have renderings to backup my project so thatll be a completely different posting. 3d animations of it turning around and showing all sides would be helpful but STILL shot designs are fine for now. There are two components to my project one similar to a watch and another component attaching to the audio device and headphones. Im looking to create it with a futuristic look similar to the pictures I posted. These are merely pictures i found to be used only as inspiration. Im looking for a unique design thats cleancut sleek and futuristic. My product differs slightly but the images can hopefully put you in the right direction of what im trying to accomplish once i get into details.

Please send an example of your voice and previous work.

Expert TRANSCRIPT Proofreader Needed ASAP (no Newbies!)

Seeking a $1 to $5/hr NATIVE ENGLISH SPEAKING proofreader specifically experienced in editing and proofing TRANSCRIPTS to audio. You can be new to Freelancer, but you *must* have experience in this area. This is a long-term EDITING/PROOFING position.

You will:

1. Use Express Scribe (or your transcription software of choice) to optimize the audio volume/settings/etc. to capture as much dialog as possible; then:

2. Proof either the entire transcript to audio, or just those portions that dont make logical/contextual sense (typically meaning an inaccuracy by the transcriber);

3. Research to resolve phonetic spellings and verify terminology (even if unmarked as phonetic) for EVERY transcript; and

4. Edit punctuation (and occasionally, but not usually grammar) along the way.

Please describe in detail the types of content youve *edited/proofed* (legal, business/marketing, IT, finance, medical, etc.), AS WELL AS your experience directly transcribing files, including how long youve done so for both, please.

For this long-term, as-needed position, you may suddenly have several assignments per week for a short while; then, you may have nothing from me for weeks or months at a time. Please expect a short proofing test before hire.

LOWEST BIDS (startup-friendly!) with MOST APPROPRIATE EXPERIENCE & SKILLS will be given highest preference.

Voice Over/Audio Recording

I am looking for a female character audio/voice over to do short scripts (a couple for now) for powerpoint presentations.

What I am looking for in a voice:


2-Perky (Katie Couric-esque)



Please submit a demo demonstrating the above characteristics to be considered.

I like to make things happen quickly and once I find "the voice" I am looking for, we will get on the move. As you can see in my history, I hit quick and stick with voice I like.

Scripts will be short to begin with (intros) so you will know why the budget is so small.

These will be very short, around 2 minutes to start. (subjective, I know but you will have to trust me).

If we can find th eright voice, the parts will grow in size and number.



To view the opening presentation and get a feel for what I am doing, watch here:

Mod Clipbucket Script To Allow Mp3 Upload

We are using a clipbucket script on our site to archive recordings of our presentations. Right now we can only upload video files. We recorded a bunch of audio files too, and want to be able to upload them using the site we have setup. The audio files could even play just like the video files without a picture, or adding a logo of type of visualizer inside the video box would be a big plus. Right now any audio files uploaded result in a Failed message instead of showing up.
Clipbucket script accepts plugins or mods to the script. It would be cool if it was done as a plugin so it is easy for me to install it, but anyway to make it work will be good. The better it is done will be worth more.
