我前幾日才看到 Alesis 的HD24，面板的塑膠質感和略嫌脆弱的感覺有點令人失望，只是話說回來，才美金 $1999可以錄24 軌，好像也不該抱怨這種組裝品質。這類的機器最令人難以理解的是，錄 96k 時(換上 option 的 AD/DA) 只剩12 軌。照講只要處理器夠強大，資料倍增也不是問題，偏偏他們設計的剛好只能做到 48k/24 軌才會有這種音軌容量變一半的奇怪設計。
這個東東真得很便宜，兩台使用起來效果應該不錯MACKIE也有同樣的產品。關鍵要是它能夠接顯示器然後EDIT那麽很理想呀。我想早晚有一天硬件廠家會推出把音源，去樣機，多軌錄音做在一起的機 器，用自己的os可以擴充。然後可以接大的顯示器。2480就是個前兆，看後邊了
Harddisk Data 的random reading & writing 一直是system 不穩定的最大煩惱,,,,從歷史上電腦和經濟環境終於讓我們不再太煩惱harddisk 的容量和售價,因此Alesis 的HD24,試圖以time base的data coding format 去達成穩定的多軌錄音,(a bit like magnetic tape recording)..從前的電腦工程師不願浪費昂貴的硬碟,所以錄下來的audio data 散落在隨機的location,現在IDE disk 便宜了,如果為了“穩定“我們可以用硬碟像用磁帶 一樣,每一軌的audio samples,有他固定的time cell,同時減低了reading & writing 時的error rate,..... 哇！！幾乎就像一部"傳統的"多軌錄音機嘛!! but how does it sounds likes ?? Might its sounds just like its own best advantage.....Cheap !!??
To 掌門 其實當sampling rate double 時,audio samples datas (uncompressed) 當然也變成兩倍,這純粹是storage的關係,不關processors的問題,這樣的模式在Sony's DASH HR 和 Studer ZDR(48 tracks down to 24 tracks when in HR mode) ﹠Nagra(4 tracks down to 2 tracks when in HR mode) 上也相同, 好處是讀寫的transporting remain as stable as in 24 tracks operation.....以Adat interface supports SMUX 傳輸96KHz 24bits的convertors 還有 Prism,RME,Mytek..等 , 此外因為high speed clocks 的 syncs problems 須要更昂貴更快,更難製作的同步clock,所以目前以double wires 傳AES 96Khz Stereo signals 也是普遍較convinced 的interfacing !!(another option nowaday is double up internal clock speed,which generally causes more jitter and error samples between interleaving,!!) To charmingguy Compares to Alesis, I should rate the Roland 2480 ,a bigger 1680 or 1880,but in technology,they are acturally a "older" concept,and even worse in audio sonic performance indeed !!.........very personal view only !! about the 林sir,I think he is coming back to Taipei for exchange the VISA recently,I should mention about your request ,see how it goes ? O.K...? However,I should go to Bei-Jing this autumn & winter,some tours with Chi-Ching are arranged,and some albums I am going to produce in mainland...might be it is much easier to arrange while I was there ...see you then !!
To: Mr72 我可能沒有講清楚原意。主要是以 Mackie 的產品為例，其處理器是用 Intel 的低階電腦 cpu，外接的 monitor 也是用電腦視訊卡；Tascam 用的是 BeOS 的操作系統，兩者根本上其實是單一功能的完整電腦 (含 hardisk、buffer RAM、cpu......)，如果將 Mackie 的產品倒放90度，它根本是一台電腦外殼，這也是為什麼它們價錢有辦法壓低。 以現在的電腦來說，再差的電腦配上再便宜的軟體也可以錄 24 軌96k/24 bit，主要只是錄音界面的問題(如MOTU 2409 或 1296 的差別)。換言之，這些廠商在設計硬碟錄音座時，也應該至少做到能處理 24 軌96k/24 bit，只是一開始保留那樣的運算能力，隨機的AD/DA 只能做24 軌 48k/24 bit而已(反正表頭也只有 24 個)。讓使用者後來再升級 AD/DA 就好，就像我們一般電腦硬碟錄音，使用者只是再多買一台 AD/DA，雖然同時間要處理的資料變兩倍，音軌數變一半，但至少還是保有最起碼的 24 軌。 相信大部份的人會希望多花25% 的錢去買一開始就有這種運算能力的機器，而不是後來升級後，反而只剩12個音軌。
插個題外話--- Mr 72 兄: WOW! Man! You're touring with Chi Chin! How cool is that!? He's one of my all-time favourite artists cos I reckon his stuff (not just his own effort only, of course) is no doubt amongst the best in all categories. And I bet it's people like you who help make his albums and concerts great! Keep up the good work!!! I shall REALLY look forward to this whole thing!!!
MR72:誰是Chi Chin!？你大概什麽時候來？過一些天可能BABY會到我們的STUDIO來看看。然後在我們的STUDIO還沒有營業的時候.第一次出吉他聲音居然是我們的boss和江建民jam。並且拍攝下來。看來兩岸閒的合 @真的會越來越多。真希望您早點過來。很多錄製DRUM的問題要向您請教。
To Shawn How cool is worked with him ??"痛並快樂著" !! To Charmingguy You would be awared when I was there !! To Jeffback Thanks for your hint,but would it be a little bit too clear......

Radar 是最早以time base format hard disks 的recorder,無論是IZ radars 24,or earlier radar,都相當穩定,,,, 只是廠商獨立發展產品的花費導至商品上架時的價錢較無競爭性,,,,a basic set 24 tracks IZ radar would cost you arround $5.000. U.S.D.. which is nearly 3 times than alesis,2 times than mackie... btw,if IZ could not hanging in market,investors might lost after service when IZ gone.......though IZ people are young and pretty cool !!...
To Bill 別誤會!我並沒那個意思,只是覺得怎麼'科技'繞了一圈,後來不過給一個和'傳統'相似的器材,.... 這樣的'科技'發展or'電腦'發展,對喜歡音樂的人有什麼幫助呢?..(okay,it is cheaper,..) 喜歡電腦的人總是希望用電腦模擬所有的功能,卻常常撹混了主題和動機.. 在AlesisHD24,我看到了'電腦'試圖找回傳統錄音的穩定特質的尷尬..也看到CPU,被當成'零件'放入錄音機'....就像老幹部所提的radar.. 我想應用'電腦'是o.k.的...但是好不好or適不適合就不一定了!! 至少現在有更多製造廠商同意'有電腦的錄音機比當錄音機用的電腦穩定得多,...
再補充一下...小弟的文字序述實在很爛! 多包涵!! 其實小弟從來都不會把digital recording 和Hard disk recording 想成同一件事,我想digital audio 已經是一種蠻成熟的產品規格,其實compact disk CD 也沒太多人抱怨... 但是harddisk recording不全然等於digital audio or CD...or a personal computer at home,..我的想法是漸趨競爭時考驗會更嚴刻,,但如果我只是要錄音,幹嘛要用硬碟,..又不保險又不便宜,..所以除非硬碟變的又便宜,又保險,...而且這個很重要....變很"安靜"...否則我實在不覺得有必要 用硬碟去保存"音樂"or Datas(CD ROM 都比硬碟感覺好一些.....）
To: Mr72 <BLOCKQUOTE>quote:</font><HR> 有電腦的錄音機 和 當錄音機用的電腦 <HR></BLOCKQUOTE>我聽不太懂前者是什麼意思，是指原設計是電腦的架構還是...？另外 Tascam 有做 DVD-RAM drive 在錄音座上，或可解決你所謂的不安全感，雖然轉到硬碟要比較久，但應該是可以接受的 backup 吧！ 我前兩天看雜誌上對 AlesisHD24 的線性錄音方式略有批評，據說會這樣設計一開始不是為了硬碟的穩定，而是 Alesis 在設計 HD24 時，當時的 ATA33/5400 轉很難穩定地支援 24 軌 24bit/48kHz 的規格，因此才如此做。我想也可能因為開發拖太久(中間破產)，現在看了這樣的設計有點奇怪。
To 掌門 我指的“有電腦CPU的錄音機“,就是泛指以錄音為主功能但將audio以digital datas 以封閉架構儲存的機器,,,(from Alesis.Mackie.Tascam..or Sony DASH ,Studer Dash...or Radars,,,or just MP3 or CD-R player.....). 反之則為一般可應用開放架構平台而具備錄音功能的個人電腦,,,,,like IBM,Mac,.. Alesis 的linear format,基本上和把硬碟partial 類似,也就是說每一tracks' datas 有一定的"位子",以求存取時的better performance（generally it is also suggested while in using PT,better have a external hard disk for storage).. ,,,,但壞處是資料存取的transporting mechanism 重任仍仰賴 hard disk servo,..or sync clock system related....fsat is cool,but accuracy is futher important to me....... 先不理storage 是disk or tape,單就recorders的servo 來看,rotating servo Heads(like "old Adat",DAT...,or most video camera player)已經比stationary Heads(like Tascam DA 98,DASH...or cassetteTape) 更難穩定軌跡,,..對我個人而言,一顆servo 能做的事,一定可以用兩顆or more side support system去做的更平順,,,但硬碟的probe.it is fast,but pretty hard to behavior constantly.."電腦界"的回答是buying a extra raid,or writing some guarding software to adding OS's obligation... 當硬碟錄音面對更高rate更多bits的data streming,其實也更顯比以前困難,,,,and surely common personal computers' system bus flowing should be able to handle,“理論上“(even brighter while in coming 2.5G,3G.or4G,,）and the accessing time of hard disk is like a lighting flash... but if they never really done a lovely job before,how could I believe they would in the future just because they have been doing for a while ?? and something worry me most is that they have never seriously thinking of this(or done),,,they just surffing along and searching if there is any $$$ they could get arround...... Please excuse me if I still could not express clearly,,it is strictly personal..but it would be longggggg for me to key in all..lets chat this later if you still interested !!
