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.

It's certainly possible, with MIDI notes,

but has anyone developed virtual guitarists for DAW's that can play a melody, solo as well as a Brian May or Stone Gossard? Queen, Pearl Jam - I had 'virtual guitarist' for one of them, but it could have been better, maybe I hadn't explored enough..
What might I consider? For strumming, as well? I have Logic Pro, Cakewalk also.

Thanks

I need to make a movie of my desktop with my own audio narration.

I have used Audacity and love it.

Is there a simply to learn tool that would let me record my desktop and either edit the audio with this tool or just let me edit the audio in Audacity?

There will be periods on no activity on my desktop, so I can adjust the age views to fit the edited audio.

Is Adobe Premier overkill? The cost is very high.

Client has audio files from town meetings that need to go on website.  Site is due to launch as early as next week.  Largest file size is 341MB.  Website is being built on Wordpress.

Can someone recommend a software or plugin we can use to reduce the file sizes.  They are not tech savvy so it would need to be something pretty easy to use since they do not want to have me do it for them on a weekly basis.  

They might be ok with a free trial and then pay afterwards if it serves their needs.

Is there any good software (free or with minimal one time fee) can you introduce in composing some commercial standard music?

Also just curious what software are used by those recording companies?

Thank you.

I use Audacity and have been recording my audio at 44.1 kHz. As far as bit depth, I have no idea, but have used the defaults.

I need to find the ideal for the best quality sound on my videos and podcasts, and find if my gear is up to it.

I have a MacBook:
2.4 GHz Intel Core 7
8 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6770M 1024 MB

And my microphone is:
Blue Yeti
Ultimate USB

purchased a few years ago.

Can you tell me the best sampling rates, bit depth, etc. for my recordings and also the maximum values my current gear can support?

Is this microphone sub-standard to give a professional sound?

Suggestions on improvements?

Thanks.

I am pretty good at recording my own voice and editing it to make it sound (almost) professional. So, I have not had to deal adjusting the volume of the whole track or a part of the track.

Now,I need to import MP3's and WAV files and integrate them into my audio script.

Aligning the start times is easy, but it would be nice to import the whole track and have the ability to MUTE the parts of the track I do not audible. This would enable me to have the entire track in the one Audacity file.

But more important, how do I adjust the volume of an entire track as well as boost and reduce the volume of certain parts of the track?

Thanks.

Hello,

What is the simplest or quickest way to convert wma to mp3 files in Windows 10?

It seems like many places want you to download an app but is that necessary/advisable?

Thanks

After tuning in to the first podcast I made, I found the intro slow and my voice muffled. Yet I know there were some stellar moments I need to share.

It's on Speaker .com

I will get the MP3 to slice and dice it into small chunks where I would assign each snippet a name: an interesting name what would entice a listener to hear that short piece...

Am I thinking about this the right way?

I would like to offer up a side-bar on my website with podcast events of mine, and when you click an event, you see the snippets that can be listened to for that event.

Are there WordPress plug-ins for this?

Thanks.

I have heard that Audacity is the program I need to learn. Prior to getting too deep into it I am wondering if it has the following capability.  If I input a one or two hour stream of music that has 20 different songs on it, does Audacity have the capability to recognize that one track has ended and then another begun? I know that one long stream can be manually split up and named but I do not need the tracks to be named anything past track 1, track 2 etc. Every recording I wish to put onto a dvd does have a minimum two second pause between tracks. Will Audacity do this for me or must I do it manually?

Hi

In my WP blog, I'd like to give my users the opportunity to sell their associated art (their music)
Now that CD's don't exist, what are the opportunities here? mp3's, iPod?
How is music sold?
Do most people have the ability to acquire this music, in practicality?

Thanks

One of the people assisting me with the marketing of a time tracking tool on my website came across this advertisement for another website https://www.youtube.com/watch?v=9E48dtx8i_s.

He swears this is computer generated but does not know which product would have generated it.

It would be good to find a tool that could give me the same computer generated voice with the level of quality found in that video.

Assistance is greatly appreciated.

It's the latest model Apple TV.
I am replacing a VCR with the Apple TV, and need the Audio and Video to be converted to connect to an old Marantz AV Receiver.

Is there an adaptor that will work and support Component as well as the 1-output Video?


Thanks

Hi experts

I have these sports bluetooth headphones.
http://www.bestbuy.com/site/jaybird-x3-sport-wireless-in-ear-headphones-blackout/5642500.p?skuId=5642500

I use them with my iphone.

I got these Jaybird x3 so I can use them while I run.  They are ok. But they occasionally fall off my ear so its starting to get annoying.

So now I'm looking for some bluetooth over the head style headphones that I can use while I run.

All the over the head style headphones I have seen seem to be made for just sitting around in your street clothes or leisure listening.
 Not for running around exercising and getting all sweaty in them.

Anyone know of some good over the head style sports bluetooth headphones that you can recommend that I can use while I run?

That won't get damaged if I get sweaty.

I just installed iTunes on my windows 7 pc and I'd like to copy a bunch of my MP3 files (some are podcasts, some are music MP3's) to my iPhone 6s. I don't want to copy ALL of my MP3's just some.
Can someone recommend a YouTube video or instructions.  the UI of iTunes is not really intuitive for what I'm trying to do.  
Or maybe I'm just not getting the logic of it.

Client is a township.  They are mandated to record meetings and post online for 90 days.  Meetings can run 3 hours in length.  Files are mp3.  Some are quite large.  

1. Is there a recommended method to posting audio on a website?
2. How large is too large?  Some files are over 300MB

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 have a challenge: Want to run Spotify (or similar software) with a pre-defined playlist for some hours and then switch to another, net-based audio source (net radio). Switching should be done at specific times during the day (radio in the morning and spotify in the evening). Is this possible to do on an ordinary windows PC? What kind of additional software would be needed?
