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.

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?

I have an audio file that has multiple people speaking on it.
I want to reduce the sound of one/2 persons and enhance  the voice of other person. it looks there is some hiss sound and some kind of noise. I also want to remove it.

As the title mentions, Realtek HD Audio Manager is consistently muting my headphones for some reason. I have tried using the microphone/headset on other devices and it works perfectly fine. But when I plug the headphones in, it works for the first few seconds then mutes. I have to manually go on the application and un-mute the microphone device in order for people to hear me online.

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.  

Express burn's error message is sense data 03 73 03, don't remember what window media player's error message is.  

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
