Articles and reviews from Zach

It is now about one week since i started a research testing  my older songs recorded iin 89 in shazam The results are impressive!You will find a detailed  technical information  on the text belo in the  numbered part The idea behind this research was first  to identify the songs of my collection prior to start a DX-music related article. i tought it could be more wqise to fist know the all posisble titles of mu older collectios  and then start writing  the article. The sense of idetitification from Shazam was also very impressive . Knowing the real titles of songs you could sing but never knew is very magnificent and more epscially for me in a first  time subject as Chinese and Thai which i never was envolved. The idea of using Shazam  was a proposal by a fellow DX consultant  last yea the time afcter a conflict with a radio fellow on two songs  with nearly the same name but diferent category. It has been  also used ...

Media coder Apr 13, '08 12:15 PM for everyone Category: Other Another very good freeware, shell extension trans coder, offering   many modes and codecs for only transcoding ! IU found this program from Lifehacker and Freeware genius  sites as for both  of them seems their favorite Here instead of making a review   I will just notice the facts after  several hours of transcoding At first the  program is quite complex as it offers: -A pane with the files to be transcoded -Left bottom  window  offering -some generic adjustments including decoder , encoder , channel and gain -Plugins (in the new version ) that includes several  decoders (including mp3 pro ) -Start and end positions -Tag transferring engine with the  ability to output fiel name based on the ID tags -Output folder options -Right bottom window offering all  codecs  available : Lame , Ogg vorbis , Nero , AAC, CT AAC 3#GP AAC,WMA,Helix MP3 < Frauho...

Some notices on DVD and memory ‘recording’ …..(only for curious people !) Sep 25, '08 8:08 PM for everyone Category: Other …..and results in several MP3 players! HI , was anyone being curious on how DVDs or even flash memories are ‘recorded’, ie how the files are set in the disk/,memory and in which order ? Being quite curious I used quite much the DOS command to test the results: C:>dir: That gives the listing of the files unsorted, or which is the sequence of files (by the time) transferred. In the following part of this article there are results from several programs tested, and results also on flash memories, including some impressions using MP3 players Results from CD recording programs All recording programs first sort files by name for the first session before the transfer session begins. Transfer is then subjected by the sorting. - Roxio : uses case insensitive sorting and then file transferring as above , So the transfer sequence is tjhis way : ! to | , 0 ...

Recommended programs and settings for ripping/transcoding Oct 2, '08 11:03 PM for everyone Category: Other 1. for conversion into MP3 : Bonk enc version 107 or 109 from their site bonkenc.org . Their Lame converter has the best audio quality surpassing any other program using this codec Recommended settings : For Hi Fi results on 128 with quality 2 (about double processing time from the standard quality setting but gives the best results) 160 or even 192 is not necessary snce it consumes 25% and 50% more space for extremely small audio difference suitable only to audiophiles Transcoding for low quality audio such as radio : 24 bit quality 2 2. For conversion /transcoding into ogg : Recommended setting is 64 kb Bonk enc is very slow , ½ of the original time Mediacoder is recommended and very fast. www.mediacoder.org 3. For transcoding into acc/mp4 for mobiles : Again media-coder using Nero or AAC plus codec Even 24 kb is OK and g...

Mar 11, '07 7:00 PM for everyone http://zlgr.multiply.com/reviews/item/18 And a notice for my A/B measurements.  In order to better measure / compare the different earphones/earbuds I have found a cabled splitter in the market , advertised as Ipod audio splitter and costs about € 4  This splitter for me has a great advantage over the typical splitters found in electronics stores: Several headphone plugs are quite thick and do not allow other plugs to be inserted on the splitter . two of the splitters I have tested so far made short connections and finally offered monophonic audio in both ear[/head]phones . In this photo yu can see on how I have made my parallel monitoring between the 929 and the Philips SHE 2610 ears . The idea is very simple with immediate results: 1.A stereo audio is heard as a line between the two ears. 2.A monophonic audio is heard in the middle point of this line , is located in the nose 3. Any differences in a m...

There were several bad links .Please read it again as the pictures are now corectly shown --------- 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 2000.Also i used several professional equipment the older days and I know very much about it. This is a abridged version of my blog in http://zlgr.multiply.com/journal/item/41 with a little more explanation in the pictorials If someone is still very boring to read this whole message ,please check the flies ...

.........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...

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.

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...
