MEDIA publication offers : a good solution against piracy? Printed media enclosures are a custom in Grece many years ago . Below you will find some of the facts concerned with the history of media enclosures , by the amateur view of a media observer looking regularly the local newsstands, and referring with approximate times Here is a short parenthesis that refers to the status of piracy in Greece that explains in short the reasons media entered into these offers . In its 2006 edition IFPI showed a 50% level of music piracy for Greece , ranking them one of the top 10 countries in earth in piracy level. But considering that the lower salary todays in Greece is Eu 750 , the price of a legal CD is at least 20, is too expensive . The pirate CDs sell for Eu5 with pirate DVDs around 7-10.As far as I can remember this was also a quite long 'tradition' still from the cassette time , when tapes on 70s and 80s were sold in …baskets. But with the worst ever audio. Even music shops those o...

BLADE ENC This is a plugin offered from the program's web site as ' optional ' . I have also installed it for testing Blade is one of the oldest freeware converters but with closed coding although recently ity has been open source . The version used is 0.94 As you may see the codec configuration is very simple . Just the bitrate and some basic adjustments with also separate channel encoding (the dual channel) Bitrates are standard with 32, 48 , 56 , 64 , 80-, 96 , 128 192 224 256 and 320 being the highest Here are the measurements with BLAde CD WAV b/W 320 14.19 12.9 22kHz 6.87 192 15,87!! 13.12 22 kHz 6.62 128 17.81!! 16.06 16 kHz /peak 800 Hz 96 18.53 16.75 -7 db<2.4k ,-4<16k,-42>16 48 18.46 16.77 -40<2.6, -17<-5, 7.5-16> -7.5 The first column is ripping time from CD of a song of 2,26 mins Secoind columns from the WAV ripped song b/w is the me...

IN this and the following articles you will find som measurenemts  for the encoders used with bonk: first let me advise you the  method  i used for  measuring 1. For the times measurements : Used - A song from a CD  of 2.26 mins ripped directly . I order no to damage the CD i then  ripped it to WAV  format -a stop watch unit from  DS clock,  a  simple visual  (and free )clock  program , with .01 sec accuracy. most of the results have +/- 0.15 secs tolerance  - Snagit one of the oldest capturing programs  for capturing part of the screen - After snagit was started capturing   i start the stop watch and then bonkenc - After Bonkenc ended its task , i stopped the timer and then the capturing - i then measure the bars progressing and do the time  subraction Here is a video  with the above methodology >>> 2. For the  sprectrum measurememnts A WAV file  is first made with  white no...

.........and reconverting your MP3s  into another forrmat ........... A REVIEW The program has been found i think in the freewaregenius web site (together with mediacoder , toibe reviewed later here ) several months ago, bvased on a very short review, which normally acts as a shell program for several freeware /open source audio codecs. The program can be found  in the adress http://www.bonkenc.org  and includes  the latest two versions  , together  with two extra plug ins. The most curent is 107 ONce you download the  program the screening is shown as below: The program has the following  specifications: - is totally free and comes with its  source - it can be just unzipped into a folder and  work . Thefore it is a green program - There are various language translations including a program that handles translation fields - Connectivity with  CDDB  for automatic  album naming (if avaialble ) - automatic ripping after a CD...

You can find it in these links (direct pdf files , please use "save as" with the right mouse click , or press ctrl + for opening into your web browser. The file is just 200 kb. multiply article geocities article in case the previous does not work The file shows the methodology i use plus a big table with compressions in wma FhG and lame mp3 vers 1 codecs in terms of spectrum analysis This file has been originally edited on 2005 Please leave here you r comments

This is an notice shown on the  same webpage and also refered here separately.  This just describes the various compressions levels and thier main use Here is a oversimplified listing  of the MP3 compressions :Notice that as the number in the left pane is higher ,  the  higher the filter and thus higher fidelity audio. The higher numbers can offer the abilities or the  lower numbers  too.   Notice: The program  used  for analysis  is Music match jukebox that offers  the  curves shown in my blog above kbps approximate usage - 8 - 11 kbps suitable for recording telephonic conversations , voice  recording . narrowband AM radio 16 the above plus high fidelity  speech, AM radio, low fidelity streaming radio 24- 32 kbps high quality speech , A...

Notice : this aricle is my 2nd arcticle on mp3 tech and appeared on 31-5-7 on multiply site . The main reason writing that article i s that many  people  are using  low level MP3 compressions (as 192 adn 256 )  that i do not think  are  so necessary  since per  my measurements  128 kbps are more than enough. To my year  wma's  of the level of 48 kbps  have neatly the  same level . --------- Given that many users on Multiply rip or covert their music in quite big files of over 7.5 MB fr a 4 minute song ,i decided to write this article to explain why it is not necessary to use very high sampling rates. At same time I will notice to you why I use the WMA format in 48 kbps to include mass material into a small MP3 player as shown in my previous reviews It is important to advise you that I was in the audio technology and HiFi's since 1980 , including also the MP3 tech form ca 1997 and my first ever MP3 player was with CD on...

MP3 comparison chart of two encoders Please notice that this is the first article i wrote abut mp3 tech analysis , depicted on 96-97 and appeared on my old geo site UPDATES ( i think made on 91-92 ): Following a series of upconvertions adn other experiments that itme i have found soem other peculiarities that are main to Musicmatch: Upconverting monophonic bit rates to stereo bit rates can cause stereo widening of these monoral audios. The lowest stereo mode i found or used was the 24 kbps UPconverting to higher bandwidths may cause / produce 'reaction /reactance carriers' . For example a 8 kb ( of 8 kHz) upconverted to 24 kb cana cause ahigher freq whistle to be heard, that can be soemtiems very annoying. please notic that this does not only happen between MP3 converions but also to convert one WAV file of 32 kHz to an MP3 file of 44 kHz bandwidth . There was indeed one reactance carrier of ca 16 kHz . The problem for this case has been corected...
