What audio format uses the least amount of memory mp3 wma wmv or wav?

WAV is normally used as an uncompressed audio storage format. It supports several formats but is most commonly used to store CD standard data, 44.1 kilobits per second on two channels. It will typically use about 10Mbyte per minute.
Both MP3 and WMV are compressed formats. They encode the data into smaller file sizes by losing some of the audio detail. There are many different compression ratios so in either case, the resulting data usage can be anywhere from 5Mbyte per minute down to Kbytes per minute. The smaller the file size, the lower the quality. A 128Kbit per second stream is usually considered to offer reasonable quality for music and at this size, music will use about 1Mbyte per minute.
As WMV and MP3 use similar techniques for compressing audio data, it is the compression settings that define how small the file will be rather than the choice of file format.

Can HDMI carry analog audio?
HDMI cables can carry audio but it is in digital format only. Any HDMI connector will be capable of carrying the audio content and any input should be capable of receiving and processing the audio in digital format. There should normally be no need to use analog audio with HDMI but there is one notable exception. HDMI shares the same video interface format as DVI, the digital display output used on computers. However, DVI does not support audio so a cable that links a DVI output to an HDMI input will not carry audio. For this reason, many new televisions have at least one HDMI input that also has an analog audio input associated with the HDMI port. This is specifically provided to cater for DVI + analog audio as delivered by many computers.
How many objects of a given class can there be in a program?
It depends on the size of the object and the amount of (virtual) memory available. However, the size of an object is not determined by the amount of memory it physically occupies, but by the amount of memory it consumes. For example, a resource handle object occupies at least one word of memory, but the resource it refers to consumes additional memory. The sizeof operator only returns the size of memory occupied by the object itself, not the total memory consumed by the object.
Which JPEG file tahes up the least amount of memory?
JPEG is a bitmap file type. There are many bitmap file types but JPEG is the one which uses the least amount of memory. However, JPEG image file sizes can be changed by how they are saved in the data loss compression feature which JPEG uses.
What is the least common memory slot found in a computer?

How much memory do you need to run roblox?
To run Roblox you need at least 512 MB of RAM(memory). Also, you need a good amount of storage memory to install the game. At least 250 MB of storage space is recommended since roblox updates often and is constantly becoming larger in file size.

What is the difference between mp2 m2v ac3 and a52?
Each audio format intended for DVD has different compression ratio and quality. There are three main types of audio: AC3 (Dolby Digital), PCM (uncompressed), and MP2 (MPEG Layer II). The most common quality of audio in DVD is 48hz (frequency), with Dolby Digital 5.1 (surround sound).AC3It's a Dolby Digital Audio. AC3 supports not only stereo, but also surround. Audio bitrate range: from 128Kbit/s to 384Kbit/s. 192Kbit/s is the most common bitrate.Surround sound must have at least 6 separate source channels. Taking a stereo or mono audio file and forcing it into Dolby 5.1 format will only waste space and provide no advantages.Pros: AC3 format has very good quality, surround sound support and very high level of compression. That's why the size of audio information is small.AC3 is the best format to use in DVDPCMCons: The main disadvantage of Uncompressed PCM (WAV or AIFF) audio format is size. It stores all audio information without compression. It's a recommended format for audio editing. Do not use PCM in final versions of DVD. Only leave it as PCM if final disc size is unimportant or if unusual distortion occurs from AC3 or MP2 compression. Common bitrate is 1536k.Pros: The main advantage of the PCM audio is excellent quality. With PCM you can preserve all audio frequencies (even outside the range of human hearing).MP2Another form of MPEG audio is MP2. Also known as MPEG Layer II and .mpa files. This format is not officially supported for NTSC video. If you have MP2 audio then do not recompress it to AC3, recompression may destroy the quality. So, leave it untouched. But if you have PCM uncompressed source, I definitely recommend to use AC3 instead of MP2. Common bitrate is 256Kbit/s.Pros: The main advantage of MP2 is good compression level and ease of audio conversion from SVCD or VCD.Cons: The main disadvantage of MP2 is not very good quality, and lack of support by all devices.
