Streaming audio and video. Using streaming audio in online music recommendation services What is streaming audio

Streaming audio and video tracks is one of the common ways to not only reduce the load on servers with multimedia data from which loading, but also to facilitate the task of playback on users’ computers, since they do not need to wait for the file to be completely downloaded.

However, this method there is a small problem. Typically, such streams cannot be saved to disk. standard means. This circumstance led to the appearance of more than several dozen special programs to record tracks to a file.

Unfortunately, at the moment best utilities for recording streams are not free. In a good case, you are provided with demo versions that are reduced in functionality or trial versions that are limited in time.

The situation became this way after the judicial systems kicked out from the Internet free programs that were superior in all respects, such as StreamBox VCR and GetASFStream. Mentions of them can still be found on dubious download sites, but in most cases the files offered are viruses.

However, the problem of recording media tracks can still be solved, albeit in a roundabout way. The first step is to use free web services for recording streaming media, which require only a link to a page with audio or video to enter. For example, a link from YouTube.

If the services cannot help you in any way, then you can record media streams while they are played on your computer. If it’s a little simpler, in the latter case, first you launch a recording program that will save everything that is transmitted to the speakers and to the screen, and then open and play the audio/video you need from beginning to end.

Note: Of course, these are not the most best ways solutions. However, they are free and available to everyone. And their potential is quite enough to solve most emerging problems.

Note: When using these programs, you must remember that there is a concept of "copyright". Of course, it is not so relevant for our country, but the concept still exists.

Review of free programs for recording audio and video streams

If you need to record videos from famous media sites like YouTube, then using online services like savefrom is enough. Just enter the desired page address with the media stream in the input field and click "download". Today there are many such services. Basically, they differ either in the list of supported sites or in the way the resulting files are provided (sending by email, various formats, etc.).

Unfortunately, these services will not always be able to help you. For example, a media site may not be supported by the service. Or the video is displayed using a unique player that uses clever loading algorithms. Or...

If this happens and the services cannot cope with the task, then you can use a workaround. Namely, record media tracks while playing audio and video on your computer. Of course, with such recording there will be a slight loss in quality, but this fact is more than compensated by the fact that you can record any audio or video, no matter where it is located and no matter how technologically it is played.

Sound and video files have a large information volume.
To transfer such files via computer networks standard digital formats require high-speed communication lines throughput. Digital stereo sound High Quality requires a data transfer rate of 1.5 Mbit/s.
Digital video of the television standard requires a data transfer rate of about 240 Mbit/s to transmit images.
To reduce the volume of audio and video files without a noticeable loss of quality, special compression methods are used, based on the removal of audio or video information that is not perceptible to humans.

Stream audio and video.
Streaming audio and video technologies have become widespread on the Internet. These technologies transfer audio and video files in parts to a buffer local computer, which makes it possible to stream them even when using a modem connection. Reducing the transmission speed of the channel can lead to temporary audio dropouts or skipped video frames.
Multimedia players are used to listen to streaming audio and watch streaming video. While playing a streaming media file, the user receives information about the data transfer rate and can adjust the playback quality.

There are quite a lot of radio and television stations that broadcast via the Internet. Web cameras are widely popular, installed in various parts of the world (on city streets, in museums, in nature reserves, etc.) and continuously transmitting images.

“Perfect for customer support videos. The ability to record screen captures and send to users that are experiencing kind of an issue or need assistance helped us to provide better support to them. This free screen recording software is perfect for customer support videos and troubleshooting. It allows me to make short videos and share directly with the users without having to send the file. Just share the link.”

“We absolutely love how much ScreenREC has improved our internal workflow as well as communications with our customers. It works great on all OS platforms (Mac, Windows and Linux)”

, Director, IT-Specialists.co.uk

“Real time-saver. When I tried Screen Rec, I realized that it uploads the video while you’re recording. I love that. That means I can record my screen, send the link immediately, then I can move on with my life. I can easily set time limits or view limits and passwords to control who can see my screen recordings.”

, Director, Regarri.com

“This is for sure the best screen recorder for mac! It helped us improve communications within my software development team. In our world, very often, what you want to say requires more than just plain words which can be a huge pain. Through just a few clicks, Screenrec helped us fill this gap perfectly by not only capturing the screen but also uploading it on to their server. And on top of that, it generates a shareable link for instant sharing. So cool.”

How often have you had to search for music you liked on the Internet? Exactly the one you heard on your favorite site ( social media, music portals). It often happens that it simply does not exist elsewhere.
Seasoned “seekers” will say that this is not so. But let's consider the average user, whose knowledge of technology does not allow him to operate by "digging" into source code pages or cache.

It so happens that most of my friends are just such users. So it was decided to write this Chrome extension (and others like it) for them.

What can he do?

• Download any audio file from any site(mp3, wav)
• Correctly identifies the original name
• Shows duration, size and bitrate
• Download on the same page as the track (without redirect)
• File preview

Try the extension from the Chrome Store

Some pictures and videos:

I will be glad to receive healthy criticism. I hope this extension will be useful to someone.
If you are interested, I will soon publish a review of the source code in another hub and post it on github.
There are also plans to port it to Firefox and IE.

P.S > There is also the ability to download videos, but in this moment disabled (there are minor problems with video streaming).
