If you’re considering purchase an MP3 player, or are simply wondering exactly how much of your music repertoire will right on to one, climate this tiny utility could be simply what you’re feather for.

You are watching: How many mp3 songs per gb

The memory, or warehouse capacity, of one MP3 player is typically measured in GB (Giga Bytes), or MB (Mega Bytes) because that the smaller/older players. However, the number of songs that your MP3 player deserve to potentially save is no only figured out by its memory capacity, but additionally by the bit rate of your MP3 tracks.

If you’re not certain of what a bit rate is, or what it has to do through things, climate the previous short article on What are bit rates? may assist explain points for you.

If you’ve currently got a repertoire of music in MP3 format (or one of the other well-known music compression styles such as WMA or AAC), then your little rates have currently been set. However, once you’re converting your music native CD to MP3 (ripping as it’s called), you should be able to choose the little rate most perfect to your needs from within your favored conversion software. 128 kbps is usually a an excellent starting point as a compromise in between sound quality and storage requirements.

This is a great tool; give thanks to you for offering such a clean and also straightforward calculator.

Would you maybe consider adding the v0 bitrate and also an choice for lossless layouts such together FLAC?

Hi Richard. Amazing info here. Ns hope you have the right to answer part questions.

I have an 8GB ipod Touch (Actually, it’s 6.8gb). Ns did no convert greater bit rate songs come 128kbps come AAC. Therefore, my iPod deserve to only hold about 700 song plus half a gb of podcasts.

Since they space NOT in ~ 128 kbps, have the right to I i think they room at 256 or 320 kbps? If I transform the song to 128 kbps, will certainly that permit me to add much more songs?

If yes to the inquiries above, how do I transform the song to 128 kbps? execute I have to delete them native iTunes and also load lock again?

Thanks for her time.

Anny is given a new MP3 player for her date of birth which contains 4GB the storage. Anny has a repertoire of 400 CDs.(a) calculate how plenty of CDs can she right onto her MP3 player.You might assume that each CD lasts for 60 minutes, and is videotaped with standard parameters for CD-quality stereotype sound. You may likewise assume the each minute the sound stored in MP3 format takes 1MB.

…back to school: 4GB = 4,000MB. 4,000MB = 4,000 minutes (assuming 1MB = 1 minute). As such number CDs = 4,000 minutes split by 60 (minutes every CD) = 66.6 = 66 entirety CDs provided your over conditions.

Thanks for the conversion information, Richard. I’ve been “googleing” for around an hour do the efforts to number if I must buy a 2GB, 4GB, or 8GB MP3 player for several of my timeless music that ns listen come in mine car, and your website was the very first that answered mine question. Many, numerous thanks.

So, your tool is really handy, I appreciate the initiative you put right into this. On another note, why are civilization asking friend how huge their library is and how plenty of CDs to the right in how much space.

mido “Average album size is 45 minutes” . Girlfriend just offered the equation in a indigenous problem and the change was provided above. Think a little, it will certainly not hurt you.

RGH right click the damn folder climate click properties, it’ll tell you the size…..

Richard, You are a really patient person, many thanks again for your scripting work. Please delete this to avoid a cascade on your blog.

Hi RichardHope to help me around a problem.The capacity of a tune in mp3 is 4minutes and 30 seconds. Download spees is 56kpbs. How much time is necessary to download this song and also what is the volume of her

if you can aid me v those information??100–160 kbit/s – standard Bitrate quality;192 kbit/s is the greatest level sustained by many MP3224–320 kbit/s – VBR to highest possible MP3 quality

Hi Richard,

Could you assist me about Computer Networking.I need to do a job on this subject which needs to do emerging the chat through multicast, this project need to realize the regimen c #. While my partner in other team have to Develop client program that interact with the server in C #. Network UDP. In the end I need to link the chat v my colleague’s server.best regards

Since everyone is so happy through this calculator, I must be missing something. I’ve do the efforts the MP3 track Calculator top top this web page in both chrome and also firefox and also the resultant greyed out firgures never readjust whether I use the the smallest or the best bit rate or adjust the storage. The is always 2.19, 3.1, 39.

What have I missed? i was in search of a ‘submit’ or ‘calculate’ button however could not check out one ~ above the type so i assumed the would instantly recalculate ~ above a readjust to the little rate or storage capacity. However no change?????

That’s functioning fine currently Richard thanks. Ns was considering purchase a sony voice recorder to record a three day convention. Since it had only internal memory the 2GB, ns was keen to check out if I might record the whole event without having to ’empty’ it to a computer. That is collection to document at 192 kbps so making use of your calculator I watch it will absolutely cover 24 hrs at the rate. – many thanks –

and many thanks for the speedy answer too.

Nice website – thanks for law this. I’m relocating from a 500MB unit come a 8GB Sansa ordered from B&H. I will have to see if the sound sacrifice (128kbps vs 250kbps) is worth being able to save 1/2 (or double, depending on how friend look in ~ it) the variety of CDs.

Hello Richard I have just to buy a 16GB Sony Walkman and put three of my CD’s right into it to obtain familier with it. When I put one more one in next day my an initial three had disapeared. What have I excellent wrong. Additionally the Walkman had actually music in once I to buy it. This is quiet there. I have about 200 CD’s so ns cannot down pack them every at once. Give thanks to you Gordon Coulling

Hi Richard

Excellent site, simply what I’ve been looking for, say thanks to you.

On a slightly different tack, i am just starting to rip all my CDs on my laptop to Flac initially. Does the top quality of mine cd drive and/or sound card impact the quality of the rip, or together it is all digital go it not matter?

Thanks again & merry Christmas

Most songs are averaged 4 minutes not 3 and half. Now a work they are also bigger 보다 4 minutes. So this is inaccurate. Ns listen come metal, metalcore, deathcore, death metal, and some songs are a half hour long. So yes, really best method to mean it the end is in between that time. So ns say around an ext of 6 minute average, since only one or two songs room 30 minute long.

Very hand calculator! many thanks Richard!

Interestingly, Nimbus Data placed a 100TB SSD ~ above the market a pair of years ago. If I’m correct, through that solitary drive you might listen to 128 kbps song for around 212 years and never hear the exact same song twice!
