调音我用的Ubuntu下的一个叫lingot的小程序。打开后对着麦克风拨弦,即可显示频率。根据频谱图和指针的摆动,我发现我的五弦音色最不纯。
测了一下我用共振法调过的琴,各弦频率是: 66, 89, 118, 157, 200, 268,相邻弦的频率比是:
1.3485, 1.3303, 1.3260, 1.2739, 1.3400,而标准的频率比应该是:
1.3348, 1.3348, 1.3348, 1.2599, 1.3348。据此可以看出琴音的准度。

If this item is on the SourceForge.net home page and you edit it, it will be removed from the home page.如果一條新聞放到首頁之后被編輯,就會從首頁刪去。所以4digits的這條新聞就從首頁拿下了。
4digits is a guess-the-number puzzle game. It's also called Bulls and Cows, and in China people simply call it Guess-the-Number. The game's objective is to guess a four-digit number in 8 times.你看看,Hi all竟然放到了第二段。以前按照文檔里面的指示,我也把新聞寫詳細點,這次我都懶得了,隨便介紹兩句完事。命運真是喜歡捉弄人,認真寫的不會上去,不認真寫的偏偏又上去了;上去了呢,又給我拿了下來。也許正是因為原來題目里面的"Puzzle Game"吸引了編輯,給我加上去了呢,否則"4digits 0.8 Released"也看不出是個什么樣的程序。
Hi all,
Eight months after 0.4, 4digits 0.8 is released today. This version features high score function, a hint table for marking and many improvements. Just download and enjoy it!
