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.

Cloud Class® Course: C++ 11 Fundamentals

This course will introduce you to C++ 11 and teach you about syntax fundamentals.

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?

Is there a tool/program that I can feed it an audio file and it will create an audio snippet of words mentioned by a voice with searchable metadata?
The goal is to create those types of gags where you have a collection of words mentioned by someone, and then you just create something silly with this.
What is this even called?  Sorry, I'm not an audio guy. Any tools for this? Should I attempt to make one in C#?

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

How can I test which mic is better?

I am looking for a mic that hears me and nothing else.

Is there a windows 10 mic test program. Not just testing to see IF microphone works, but how well microphone works

What services can be restarted in Windows 7 if audio fails when joining a WebEx
conference? My system audio for mic and speakers tend to work fine for Zoom meeting
and Skype. WebEx has had problems and I have to have it call my cell phone instead of
just using the headphones on the laptop.

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

Hi,

At present, we are using Spotify as our source for playing quality music on Denon AVR X4300 through our Dali speakers.

We would like to have the best quality sounding music.

Which music streaming service offers the best sounding quality music, to be played on Denon AVR X4300?

Thanks,

I am responsible for recording training sessions and I need a way to obtain an improved recording of both the presenter as well as participants questions.

I believe the best option is to find a unit that includes:
- 1 lavalier microphone - wireless (for presenter)
- 1 desk microphone - wireless for participant
- 1 microphone mixer/receiver (two channels is all that I require) - must have an output jack with proper impedance to feed into a MacBook Pro audio recording the two channels.

Another option: bluetooth mics with Mac OS software audio mixing.

I don't have much of a budget so ideally, I am looking for a unit that is under $350.

Challenges:
- Most of the models that I have looked at are either more than $350 or are packaged with the wrong types of microphones (i.e. handheld mics or 2 lavalier mics).

Thank you for your advice. :)

I will soon be starting a podcast that will ultimately feature 2 or 3 episodes weekly. I travel a fair amount, so I know that having a system in place that would allow me to have automated uploads on certain dates and times would enable the episode updating to be a smooth process.

"Uploads" may be a little off the mark. I already have some cron jobs ON a website (freelanced out, since I am not a techie) that replace existing files on he website each Friday with new ones at a specified day and time on a weekly basis that has run very well for a couple of years now. I upload the new files on Wednesday or Thursday at my convenience and that's all I have to do.

To be sure, the names of the uploaded files are exactly the same as the ones being updated (or simply written over, that is).  I have not yet dug deeper into the names required for podcast files, if there are any such requirements, and want to get an expert view of what I want to do, as described.

I did some searching on Google, but they continue to descend into Internet Hell, insisting on providing search results that do not fit the search terms. On a recent trip. I needed to find a laundromat to do a load or two of laundry and a search on "laundromat" with the city name resulted in a list of DRY CLEANERS! Not even "close but no cigar" as far as I'm concerned.

I don't know anything yet about reading/writing/manipulating mp3 and mp4 files, but I'm trying to learn.  I need to write a program that reads in mp3 and mp4 files, silences some of the audio portions, and rewrites out the final file.

For an mp3 file, I can use ffmpeg to convert it to a wav file and process and write it back out as an mp3.  I don't think a wav has any messy internals.

For mp4, what with variable bit rates and metadata and such, I don't know how to approach it.  I need to read the mp4 file, modify the audio portion only while staying in sync with the video, and write out the mp4 file again.

My preferred langauge is Python if at all possible, but I'll use C# if I have to, and Java as a last resort.

How can I do this?

Hello

I was wondering if they is a media player that support multi instances which I can open each instance with a different settings.
What I am trying to do is to open for example VLC player over and over but each time with a different audio playback device - but it  always opens it with the last saved settings...Tried some more players and they work the same

Is there a player that support this? or is there a parameter to define maybe via command line to open each instance with a different audio setting?

Thanks

Hello

I have a question regarding multiple audio steaming form a single PC.

We have Digital Signage set up which is working with Monitor Anywhere software. Till now we have displayed only static material on 20 monitors which are connected to 2 workstations – one per each floor.
And now our marking tem a would like us to start displaying promotional videos which require sound. Monitor Anywhere support are recommending us to download and buy Virtual Audio Cable  via their site:
http://new.monitorsanywhere.com/product/virtual-audio-cable/
But according to them, It will only steam a single audio channel on all 20 screens. But…we need it to steam multiple audio channels over multiple screens – each screen has its own playlist…

Can VAC do that? Is that possible? Is there a different solution for that?

Thanks
