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.

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?

Need to convert MP3 to text on a Mac

I can swear I did this on my Mac but I need to use an MP3 file as the source

Can anyone remind me what built-in Mac functionality there is?

I need MP3 as the source.

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 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?

Dear EE experts,

We would like to ask on how to make or create a flash drive auto play any mp3 music inside of it, to any music players that have USB port.
Because some players are not updated, and when we insert the flash drive that have music inside, it can't be read, but flash drive has no problem...

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?

Does COMCAST have poor quality phone service?

I switched yesterday from Verizon FIOS to COMCAST and had terrible telephone calls today on the land line.

I think we were sold >100 GPS upload speed. So, I doubt the poor quality is due to a slow internet connection. But maybe the old Verizon FIOS phone number was what they called a POTS line, a Plain Old Telephone Service line. Those were the ones where you cold hear pin drop.

Did I move from a POTS Line to an Internet based phone? And is that the cause of the major drop in quality?

My new modem is...

Xfinity
Dual Band Wifi
802.11.ac

The phone cable goes into the back.

Would an Internet phone do better?

Is there anything I can do?

I really despise having poor phone quality and may go back to Verizon to escape a bad connection.

Suggestions?

Thanks

Hi,

We are unsure whether to use Spotify or Tidal for streaming music.

We would like to use the best music streaming service.

Pros for Spotify (Premium):

- We have a lot of albums and playlists setup with Spotify
- We are familiar with Spotify's interface.
- Spotify (Premium) is €10 a month where Tidal (HiFi) costs €20 a month

Pros for Tidal (HiFi):

- Tidal has lossless audio quality of 1411 kbps
- Tidal seems to have a larger catalog of songs available

I heard that you can't hear the difference in audio quality past 320 kbps.

We would like to only use one of these two music streaming services.

Which service would you recommend as being the best audio streaming service between Spotify and Tidal to use?

Thanks,
Robbie

Are there video encoders that encode video in fixed duration streamlets and repeat audio frames if the duration of audio frames is different from the duration of a video segment to fill up the video streamlet?

Placing a video of me on the side of a presentation.

I have seen this done with great effect. The person leading a presentation has slide after slide and can appear in the corner or center, at will. That person is the speaker and the one leading the pitch.

Please explain how this works?

I always thought you'd need a green screen behind you to make that work, but apparently not.

I would use PowerPoint on a Mac.

Thanks

Hi,

We have plans to test the audio quality for songs played through Spotify on different audio quality settings as well as compared to songs played through TIDAL.

The ideal situation would be that we would play a song on Spotify for example and the audio quality would display through app/software as 160kbps or 320kbps.

Is there an Android app or Windows software that can be used to display bit rate of a song played?

Thanks,
Robbie
