Digital Audio

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.

Hi
I wrote a lot of music and am curious about the potential of spotify.

Do kids really listen to it as much as it seems?

Taylor Swift had an entanglement w them, but that was sorted out, concerning payment to artists.

Is this only for seemingly professionally managed artists? who can play gigs on a moment's notice?
Didn't some dude put a song he'd recorded at home on and it became huge? What happened to him?
Thanks

I have always used iTunes for my music but finally got tired of them updating it every two weeks so I'm trying to set up Windows Media Player.  The first thing I noticed is that you can't drag and drop folders into a playlist like you can on iTunes so how do I create a playlist that I can put my music in.  I created one playlist (gave it a name) and attempted to transfer a bunch of songs into it by dragging them but it won't accept them.

The music is in a sd card which shows up on the computer as Drive (F). I know that it found the music because I can see a bunch of songs in WMP but they are not "by folder", the way I have them categorized.  i.e., Country, Jazz, Big Band, etc.

I tried restarting and using different windows browsers.

Highly specialized: is anyone familiar with the audio program GOLDWAVE?

It's a powerful audio processing program, but I am having trouble understanding some of the instructions on applying the effects across many multiple files.

If you know anything about the program, please let me hear from you!

Need a Movie recording program for Mac

I use iMovie sometime, but can not find how to set my microphone. My Shure microphone with a U-PHORIA UM2 shows up as CODEX on Audacity. Can I use this with Movie?

What alternate movie tools are there?

Can I use Premiere Pro? If so, how do I record? And can I set my Mic.?

What other tools are there to record my video, and use my CODEX? I have High Sierra


Thanks

I am trying to digitize cassette tapes using Audacity 2.2.2 and am not having much luck.  I have looked at several You Tube videos but none of them address my issue.  The problem I'm having is that even before I connect  a cassette player into my computer, If I click on the microphone in Audacity and select start monitoring,  I can see activity on the mic bar but can not hear anything.  If I try to record that activity, it does not record so when I play it back, I hear nothing.  The computer I'm using is HP ENVY - 15t -k200 CTO Notebook PC - Windows 10.

I believe it has to do with the selection of the type of input on the program but I think I have tried them all and can not hear anything.  Aside from this issue, am I right in thinking that if you connect an audio signal to the computer, that the sound should now come from the computer?  (like using a speaker?).  If so, that doesn't work for me.  What do I have to do to be able to hear the audio on the computer?

Hi
I am stucked in a project, where I have to convert some audio:
The Audio is PCM 16bit big endian 16Khz stereo & Ulaw 8bit 8000hz. Have to be able to go both ways.
Do you have any recommended Libs or even better software examples that will help me doing it :)

I get the audio in the PCM format as Callback data.
static int stream_GSMdata_2_ulaw(int16 id, char* data, uint32 size)
...
And after the conversion to Ulaw I need to send the RTP packets in 60 ms chunks (480bytes) via UDP:
 SendRTPData(myData);

Any help is appreciated :)

Cloud Class® Course: Amazon Web Services - Basic

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

I have a client who uses Windows Media Player 12 in Windows 7.

Recently (he doesn't know exactly when), his Playlist list suddenly includes the names of many non-music folders (his Simply Accounting, for example), from his Documents folder.

If you right-click the playlist and select Open File Location, you can see they are documents in random folders (looks like from Documents).

Occasionally you can see a status message at the bottom of WMP saying (can't remember the exact message) that it is scanning a folder for updates, and the folder it is scanning is *not* Music, but rather the c:\Users\Owner folder, one level above Music, Documents, etc.  Is this normal?

I can find no settings at all about where WMP looks for music or playlist location, etc.  Can anyone help?

Thanks.

I have a collection of audiobooks on MP3. I would be interested if anybody knew about good MP3 app that has the feature to be able to rewind the last 15 or 30 seconds of the audio track instead of rewinding all the  way to the beginning of the audio track.

Thanks.

There are just so many apps out there. I have tried a few different ones. But if anybody can help out with something that you’ve heard about that works well for that, that would be excellent. Thanks

Using a clip-on Mike with my iPhone 7 video recorder?

I have a microphone that does well in the wind. So I want to use it for a video on my iPhone 7.

I have this connector adaptor that converts from a round plug to the flat one used by the iPhone 7.

What do I need to do to make this work?

Thanks

Hi,

I have an on-hold audio file which is played when we are waiting to join an online conference. The music is played down the phone line.

The problem I have is the audio file, which is just a regular MP3 file, sometimes cuts out while playing and I am not sure if this is because the file is not suitable to play on a phone line - it drifts in and out of the music, especially when the music is quieter.

Is there anything I can do to make the ranges of the music file suitable for a phone line or should it play ok? Wanted to ask for anyone's thoughts/opinions.

I subscribe to several popular magazines such as Time, Smithsonian, National Geographic, and Reader's Digest.

I don't have the time to read these magazines but do spend several hours a day commuting and driving around on business.

So are there any audio versions of these magazines I can listen to? If so how can I obtain and listen to these audio versions?

Need a microphone to do a video outdoors

My BlueTooth microphone and MacBook onboard mic. were terrible in the wind. The iPhone 7 was the best, but still not very good.

I find that wind causes terrible background noise, and see the TV people use a big foamy mic. on windy days.

What can you suggest that is not expensive and blocks the noise?

Thanks

I would like to recognize sounds within an audio stream.  For instance, a doorbell.
Basically it would be the equivalent to using OpenCV to identify a face within a video stream.
So I am looking for the equivalent of an OpenCV library for audio (rather than images/video).  Or perhaps some cloud-based solution -- although I have not see anything on AWS or Azure.

I cannot get windows 7 computer to play back .wav files.   I've tried Media Player, VLC, Real player.  It must be missing a codec pack but I cannot find anything online.   Any help would be awesome.

Cheers.

Is there any way of bookmarking the MP3 music location on an iPhone X?

I'm currently listening to some dramas using my iPhone X (that are each one hour long). I have several hundred of these dramas saved on my iPhone.

I have no problems when all that I listen to is these dramas (when I listen to them sequentially) since I pause listening to these dramas and then go back into the iPhone music app and continue listening from the point where I left off before (when I want to continue listening to these dramas).

However, whenever I listen to other MP3 music files I always lose my place as to where I have left off listening to these one hour long dramas.

Is there any way (or are there any apps I can load) which will allow me to bookmark or save the exact location of where I am currently listening to these dramas so I can continue listening at the exact point where I left off whenever I want to listen to other MP3 music files?

I installed a new aftermarket stereo in my 01 Tahoe. Everything worked but when I turned the truck ignition to on from accessories... I lost all sound. I pulled it out, opened my door to reset everything and plugged the stereo back in. Started the truck and the same thing happened. I can only get the sound back on by turning off the truck, open door for reset, unplugging stereo, plugging stereo back in and turning truck key to accessories. I tried the deck in my buddy’s 01 Tahoe nod it worked fine. I tried putting his deck in my truck and the same thing happened. I put my stock one back in and it works fine. I’m completely stumped by this?! Help?!?

Assume we have 5,000 audio files of a particular person lecture and assume that that person got died years ago.

Now how to translate the audio files to text.

1. Assume need to upload a audio and correct the transcription based on the pronounciation and fix the transcription errors
2. Repeat the process for couple of files to achieve 100% accuracy
3. Convert the remaining audio files to text

Which application - open source or commercial which has this capability and can achieve more than 90 or 100% of accuracy.

Please kindly suggest with opinions and comments.

Need a voice support that is not TOO loud

I need to give a tour to about 10-20 people in a public area, but my voice does not carry very far. And if the wind is up, it's even harder.

But I do not want to use one of those megaphones. They are loud and use up one hand. I would prefer some sort of clip-on microphone, that uses BlueTooth to connect to portable speakers.

Can I WEAR a small speaker? Is that possible?

Or I guess I could pull a small speaker behind me, but that would also need a battery.
 
Suggestions?
