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.

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#?

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 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

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

We use a Sony Handycam camcorder to record amateur sports team matches.

We have been using the software that has come with this camcorder called PlayMemories Home to merge these videos together.

This was done on a Windows 10 PC.

The problem is that we have experienced a lot of problems trying to merge videos together using the PlayMemories Home software.

This software does not seem to work with merging videos if the formats of videos are different.

What would you recommend as a better product than the Sony PlayMemories Home software for merging videos.

Thanks,
Robbie

Hello Experts!!

I am in the need of creating an automatic process that automatically extracts the audio of an 60 minute long MP4 video stored in a folder, converts it to AAC format and then stores it in blocks of 5 minutes.

I wonder if there is an already-existing tool that I could implement to automate this process?

Thanks a lot.

I have tried to convert my mix cds to mp3 without any breaks between the crossfaded tracks.  Each time I try it there is a slight pause where the tracks blends in.  This is very disturbing since I created the mix cds to have a continuous flow of uninterupted music.  Is there any way for me to create a mix mp3 file?

I am actually trying to implement text-to-speech conversion in Salesforce by hitting a third-party api.

When i send the request through Postman, i get back the proper response in .wav format. However, I'm not being able to handle this reponse programatically in salesforce end, as I am not able to store the response in any audio object.

Any assistance would be greatly appreciated.

Thanks in advance.
Abhishek.

I have finally managed to get my Cool Edit pro up and working on Windows 10. I am downloading directly from a recording desk via a USB interface. All the settings are the same as on my other computer and the device setting box on the program is recognising the USB device. But nothing is being recorded. Any ideas?

hi, Whatsapp archives audio attachments as .opus files. I have saved them to a dropbox. Surely there is a way to play them on a browser without going through a complicated series of conversion steps. I need this to work for non-techies who can click on a link but that's as far as I expect the user involvement to go. I can generate the links if there is a site that will stream the opus files.

Can anyone suggest a site? Something like URL WWW.CLEVEROPUSSTREAMINGSITE.COM?MYOPUS=MYDROPBOXLINK

Thanks

Hi, Appreciate it very much if anyone can help.

I want to burn a few songs to a CD for a friend who is in a hospital.  But tried window media player of microsoft , Express burn of NCH Software and a few other burning software, have not been successful.

I am not sure what is wrong.  I used a disc which is Sony CD-R 700MB.  

Is there anyone having any idea of what is wrong?  Very frustrated at the moment.  Thanks a lot.

I just realized I have set up 2 different Itunes accounts under 2 different email addresses I have. I am trying to add music to a 2nd generation ipod shuffle but it seems it will only sync with one library or the other, wiping out all music under my 2nd account. How do I merge the two libraries?

I want to create a video editor software for my graduation project. But I first need to learn about digital video principles, what are codecs, containers, formats , mono vs stereo , resolution , sound processing ....etc (to use ffmpeg / mlt framework properly and know what I'm doing and how they do that when I use them)
The software should be able to transcode , edit , add effects and most other functions that are found in professional video editors.
What kind of knowledge should I have ? what to read and what not to read?

I bought many books about this topic , but they are talking about irrelevant stuffs , like pal & ntsc for TV and cables , a lot of math ..etc

Please let me know about the topics I need to read , books to get , any online references
