Digital audio is technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form. Following significant advances in technology, digital rapidly replaced analog audio technology in most areas. Digital audio systems may include compression, storage, processing and transmission components. It is important to distinguish between the audio coding format, the codec performing the encoding and decoding of the raw audio data, and the container file. Common file formats include .wav, .aiff, .au, .m4a, .mp3, .wma, .ra and .raw.

We have a series of audios of conferences and have categorized them by presenter.  Since windows folder displays audio with 'Contributing Artist, Title, Album, etc.', we want to place the real authors of each audio.  We  can do this one by one, but looking for way to change 15 audios authors with one name (and do the same with the rest of audios we have).  How can we go about it?

I had this question after viewing Cord to windows 10 laptop.

See previous question.
Based on pictures off front and back; do you know model number so i can contact company.
Also assume that there is an amp or base box.

Maybe this is a set.

This was purchased from another person without the cords

hi
I have written a ton of music, say 70 songs.

I am 39 years old. I'd like to get my music out there. I am not inclined to try and do the band thing *again*

I know the money in music is gone, now that CD's aren't sold.
Taylor Swift makes 0.004 cents a spin on a tube or something, right?
I'd just like to get my music out there. Are there any options for me?
I live in Wilmington, NC, which is called 'Wilmy-wood' - Hollywood East! lots of TV is shot here.
Can unknown people walk up to  a producer and say, wanna listen to my stuff?

Thanks

I'm using Windows Movie Maker to create a video for a funeral.

I'd like to use the song "I can only imagine" by MercyMe.

Can someone please point me towards a procedure to purchase a song from iTunes or elsewhere, and download it in a format that can be used in Windows Movie Maker?

OR ... I actually own this song on a CD.  Is there a way to copy just that song in a format that Windows Movie Maker can use?  

Thanks so much.

I need to photograph and take videos at great distance, but find the device:

https://www.bhphotovideo.com/c/product/838756-REG/Canon_520_B_PowerShot_ELPH_520_HS.html

too grainy.

How do I max out the resolution? I think such a great camera may work fine for me, if I could adjust it.

Thanks.

I'm trying to install Avid Media Composer for Windows, but it's a version I bought 10 years ago and never used.   I'm running Windows 7 Home Premium now.

It seems to have installed without crashing, but there are some things amiss.  There was a dialog box during installation saying my version of Windows couldn't support this operation.  

Second, after installation completed and I reboot, there is no entry in my programs for Avid.  So I located the executable and tried to run it, but received another dialog box saying it could not find Dac32.dll.  I searched for what this file is and found at answers.microsoft:

The dac32.dll file is a Digital Audio 32 Bit Copy Engine created by Christoph Schmelnik of Denmark.
I would suggest you to re-download that program from manufacturer’s website and install it.

I can't find the manufacturer or this file.  All I seem to find are suspicious sites charging money for dll's.  

Questions:

1) Where can I get this Dac32.dll file for Windows 7?  I would have thought Avid would install it, but something failed there.
2) Is it possible to upgrade my version to work best with Windows 7?

Other suggestions?

Thanks!

I have an iPhone 6 with the latest OS update.

I would like to use the phone for audio note to myself. And rather than using the cloud, it is okay to store locally and require the phone's plugged into my MacBook to be uploaded.

Thanks.

On Demand Webinar - Networking for the Cloud Era

This webinar discusses:

-How SD-WAN changes the way we look at networks
-Best practices customers should employ moving forward with cloud migration
-What happens behind the scenes of SteelConnect’s one-click button

We have 2 large screen / HDMI input TVs.  We've been paying for 2 cable boxes - 1 is a (whole house) DVR and the other is just a cable box.  There's only 2 of us in the house / we never watch tv on both TVs at once.

I can return the 1 cable box and save about $12 a month, I'd like to be able to feed the 2nd TV (now without a cable box) with a signal from the HDMI output of the DVR cable box.  Yeah, we have to run between the 2 TVs to change channels, etc.

What's the max cable length for an HDMI cable and still have a usable signal at the far end?

I'm familiar with coax and A/B switchboxes and signal splitters to get the signal to both TVs (and either use the A/B switch or just splitter depending on signal quality). But don't know about HDMI.

Is there an equiv to a coax splitter for HDMI? Does signal suffer? or is it digital so it's OK if we are within that max length above?

Or is there an A/b box to split hdmi?

And is there a way to get the remote's signal from the 2nd TV down to the first? (that gadget that you clip the lightsource in front of the DVR box's infra red receiver?

is all of this going to cost more than the $12 / month?  or do you have some other ideas?

Hi experts,

I have noticed on a couple cars that have a USB input for the car stereo it exhibited the following issue.

I have a SanDisk 128GB USB flash drive. Looking at the file system the flash drive is set to FAT32.

I have 454 albums in mp3 format stored on the flash drive.

So in the flash drive there are 454 folders. One for each album and each folder contains the mp3s of that album.

When I copied these 454 folders onto the flash drive i did it all at once so I selected all 454 folders and clicked copy and then pasted them onto the flash drive using windows explorer.

So that transferred them onto my flash drive.

So then when I plug the usb flash drive into in the USB input on my vehicles stereo.
My stereo reads and plays them fine but I noticed that it only recognizing 96 albums because when I go through the selection on the stereo's screen it only lists 96 albums.
This stereo is the stock stereo that came with the vehicle.

But in my previous car I purchased a JVC after market dvd stereo and that stereo did the same.
When I plugged the usb flash drive it didn't recognize all the albums on the flash drive either.

Am I missing something?
Anyone ever have this issue? Do USB inputs in car stereos have a certain limitation?
I have tried several different usb flash drives but they do the same.

Hi
I have a recorded lecture which I recorded on my mobile using smart recorder android app. This is a .wav file of around 180 mb.
There are following issues with it -
1) some places the sound volume is low.
2) There is disturbance in sound and although loud but one cannot properly understand what is the person speaking.

please suggest some tools which can remove these defects.
Main issue is to remove the disturbance so that one can hear words clearly.

Thanks

I can't burn a mp3 file lasting over 80 min. on an 80 min. CD.  It's been done however and I can't figure out how he did it.  He burned 1:25min on an 80 min. CD.
How can I do this.?

I am helping out a client that is surrounded by the 2.4ghz wireless band frequency. We added a Ubiquiti LR AP PRO wireless Access Point to the network. Her computers are now running great on wireless on 5ghz; however, Sonos only works on 2.4ghz. Is there anything I can do besides run them wired? There are so many 2.4ghz networks that Sonos will only connect from about 20 feet away no further.

I want to take a tv commercial and extract sound from it. I want to keep the "sound" of the words, i.e. the voice but I want to "blur" the words. I wonder if anyone knows how I might do this with something like audacity? I don't want to loose the tones of the voice, but I don't want the words to sound like words or even language, more just like music.
Thank you!

I have some audio from a radio talk show. my intention is that it's not high fidelity / could even be mono.  I want to get the smallest file size without too much degredation considering it's just people talking.

I am using streaming audio recorder and chose MP3 for the output.

For example, 1 file I have is 2meg and 1 min 30 seconds.  the properties of the file says bitrate 173 bps.  Not sure if that's high / low fidelity.

I'd like to have the smallest size file for audio.... and also, using audio to video converter websites, I get an mp4 that's 2MB also (static picture or black screen would be fine).

What are some things I should know / do to get the smallest files for spoken word audio?

thanks!

I have the following
- 2009 Nission Cube with the factory stereo (.8" AUX in)
- Bluetooth to .8" converter
- IPhone with 16 Gb RAM, 5Gb data plan,  Plex Media Server client,
- Home-based Plex media server running Centos with 500 Gb  Music.
- Windows 10 Virtual Machine on Server running  Itunes with all media loaded in library.

Currently, I stream all my music from my home server to my iphone while on the road.
I use the bluetooth / .08" adaptor to get the music from the phone to the stereo.

Downsides
- Sucks my data plan
- Plex interface doesn't lend itself to voice control.

I've considered ITunes match, downside is it still sucks my data plan.

I like the idea of a car computer. I'm an IT engineer and have lots of old laptops, etc.

Goal is to have 500 Gb of media local to my car and some sort of voice activated control to select it.

I'm willing to invest in hardware and software.

- A car receivers that have a USB external storage and some sort of  IOS interface
- Running MAC OS on a laptop with itunes /all media and some sort of hook into itunes on the iphone with audio coming out of either the Ios laptop or the phone?

Hi
I am getting a Jupiter - 80 keyboard for my new band, but there are quite a few places to buy it from.
The one I have now has broken buttons, and is still under warranty.
I've sent for a mail-it-back-and-get-a-refund, but I have to buy a new one somewhere else.

I can find a new one for $2499 on
Full Compass
Is there a better option somewhere else?

Thanks

Hi

My new Jupiter-80 is okay, as a Synth keyboard.

I am used to my clavinova's perfect piano setting.
I can only get hints of my Jupiter's piano setting. It seems to always work in halves, upper and lower.
How do I make it ALL piano, no synth?

Thanks

Hi

I have ordered a Jupiter 80 keyboard for my band.

It seems very advanced.

Does anyone know if it can do chord recognition, and appropriate bass note addition? I may have missed it in the sheet.

Thanks
