What is digital Media? By sphyenx.

Well its music of course. Say you love to download music there well are many known formats. Im sure most of you know mp3 format (mpeg3). That is not the only format, sorry. There are actually a few. Wave with the .wav extension is one of the most popular formats for sound quality. It is also know to be very good with browser support so it can be used in many browser’s with out any separate plug in’s. The only downfall with waveform files is that they are relatively large. NOT good if you don’t have a huge amount of web space. Files can be as large as 50meg’s. That’s a lot of data. Another file format that is very similar to wave, are Audio Interchangeable format (AIF) with the .aif file extension. They are large, and very good with sound quality. They are identical to .wav’s. The most popular to the many internet pirates would be mpeg3 format, as you all would know as mp3's. They are every were, KAZZA, http://www.suprnova.org etc. Every ones got them. Too bad I rip my own cd’s Im not a pirate. They are so popular because well they are fairly small. They are compressed audio. Now don’t be mislead even knowing they are compressed they have very good quality. Now they can be streamed over the internet much like aif, and wav. But require a plug in for your browser. A downfall with mp3's is the fact they cant be zipped, well they can be put in to an archive. But the files will not reduce in physical size. Why would you expect them to be after they have already be zipped down to the core with the format they are in right now. Another file type I will discuss are Real audio. These files have the .ra extension ans they can be streamed over the net. They are very small and the quality suck’s. You need a plug in and/or a player to play them. My opinion is they shouldn’t be used, but what’s my say in that. Now for my finale. MIDI (Musical Instrument Digital Interface), they are awesome if you don’t like the singers voice. LOL. They are a sequence with several extensions .mid .cmf .rol, they are files that play music with out voice, they are good because they can hold a long sound, much like Piano etc.

Thank you for reading my short tutorial on Digital Media, sphyenx.

A concise, modern follow-up to : "digital media" for a music streamer is the whole delivery pipeline, not just file extensions. The important pieces are the source master, metadata and artwork, how audio is encoded and packaged, how it is hosted and delivered, and how the player consumes it. Think in terms of a repeatable workflow rather than a single file type.

Practical workflow for reliable streaming: start from the highest-quality master (retain higher bit depth and sample rate during processing), apply consistent loudness targeting so tracks play back at similar perceived levels, avoid repeated lossy transcodes, and produce multiple encoded renditions for adaptive delivery. Package for HTTP-based adaptive streaming (HLS or DASH) when targeting many device types and network conditions, or provide progressive downloads for simple playback. Host on infrastructure that supports byte-range requests, proper MIME types and CORS headers, and use a CDN for global scale. Use an HTML5-based player with Media Source Extensions for adaptive streams and verify cross-browser/device playback.

Troubleshooting notes and cautions: if seeking fails, confirm the server honors Range requests; if artwork or metadata do not appear, check the container/tag format compatibility; if audio sounds clipped or uneven, re-check loudness processing and avoid double-encoding. Ensure legal distribution rights before publishing. For video (as planned), apply the same pipeline ideas plus codec, container, resolution and bitrate ladders appropriate for target devices.

My bad, i should have labeled the post Digital Sound. Because I didnt get in to Video output etc. I will in my next review on Digital Media.
