Useful MP3 Manager & Repair Tools (Lyrics, Tags, Library)

1. Tags Tools:

  • Tags&Rename: as I said, it is the best application to manager your MP3 tags, see my post for details (more than 3,000 songs for me).
  •  Winamp and iTune: still useful for tag-editing with a few songs

2. Lyrics Tools:

  • iTunesFriend (freeware): Good application for ENGLISH Lyrics downloading with your iTunes Library. (Download Link)
  • MiniLyrics (freeware): Google application for CHINESE and ENGLISH Lyrics downloading. Better use it with winamp intro play plug (Download Page)
  • Winamp Intro Play Plugin: use it with minilyric to get lyrics quickly (Download Page)

3. Repair Tools:

  • MP3 Validator (freeware):  Sometimes, you will find iTune and/or iPhone can not play some MP3 songs. This application can fix them for you. (Download Page)
  • Switch: If your mp3 cannot be fixed with MP3 Validator, you can use this application to rebuild MP3 file.You can also convert other formats into MP3 with it. (Download Link)

4. Convert Tools:

  •  Monkeys Audio & LAME 3.98-final: Rank-AAA Software for conversion. You can generate high quality and relative small size MP3 (VBR MP3) from APE or other formats music. For details,go to my post.
  • Switch: it is not a good software for conversion coz I found it may give the wrong time and bit rate after conversion.

    使用Monkeys Audio转换APE到MP3

    注:部分内容转自网络

    所需要软件: Monkeys Audio 3.99版本LAME 3.98-final

    所需要的补丁:APX文件 (我自己编辑的)

    APE格式是喜欢在计算机上尝试HIFI的朋友们所钟爱的一种音频格式,它提供了无损的音频压缩和实时音频解码。在计算机上使用时,这种编码格式无疑提供 了最好的音质和非常方便的使用性。但是对于MP3播放器这些随身听音频播放器,这种格式目前仍然缺乏有效的解码支持,而且其编码后“臃肿”的文件大小,也 让人又爱又恨。其实我们用来编码APE格式文件的工具Monkey's Audio不仅提供了APE格式文件的编码功能,同时也提供了非常好用的APE解码和APE于其他音频格式文件的转换功能。

    言归正传,网上这类转换的文章多不胜数,但是抄来抄去,内容都一样;要命的是,都不成功。所以如果你想自己转换成好的MP3,请跟我的来。

    一、准备工作。

    下载Monkey's Audio,假设安装到C:\Program Files\Monkey's Audio。
    下载LAME和APX文件,并把解压缩得到的一堆文件放到C:\Program Files\Monkey's Audio\External中。
    检查一下所下载到的APE文件,一般会包含两个,CDImage.APE 和 CDImage.cue。如果是用的其他文件名,建议修改成CDImage.APE和CDImage.cue。

    二、选择开始菜单中的Monkey's Audio菜单下的Make APL's

    打开CDImage.cue文件,转换之。这样在和CDImage文件所在目录下会得到生成的APL文件。注意这里可以选择输出的文件名格式

    三、选择Monkey's Audio为Decompress方式(Ctrl+2)

    用monkey's Audio打开刚才生成的APL文件,把APE文件解压成若干个WAV文件。

    四、选择Monkey Audio为Compress方式 (Ctrl+1)

    打开刚才生成的若干个WAV文件,然后勾选External项->External->Lame->Configure项中填写 -V0 -q1 。随后点击Compress,你就会得到相应的MP3文件。(注意,这里可以在Option里面选择Tagging功能,这样就可以在iTunes或者Winamp等播放器中看到对应MP3文件的Tag)。

    T检验、F检验和统计学意义(P值或sig值)

    1.T检验和F检验的由来

    一般而言,为了确定从样本(sample)统计结果推论至总体时所犯错的概率,我们会利用统计学家所开发的一些统计方法,进行统计检定。

    通过把所得到的统计检定值,与统计学家建立了一些随机变量的概率分布(probability distribution)进行比较,我们可以知道在多少%的机会下会得到目前的结果。倘若经比较后发现,出现这结果的机率很少,亦即是说,是在机会很少、很罕有的情况下才出现;那我们便可以有信心的说,这不是巧合,是具有统计学上的意义的(用统计学的话讲,就是能够拒绝虚无假设null hypothesis,Ho)。相反,若比较后发现,出现的机率很高,并不罕见;那我们便不能很有信心的直指这不是巧合,也许是巧合,也许不是,但我们没能确定。

    F值和t值就是这些统计检定值,与它们相对应的概率分布,就是F分布和t分布。统计显著性(sig)就是出现目前样本这结果的机率。

    2. 统计学意义(P值或sig值)

    结果的统计学意义是结果真实程度(能够代表总体)的一种估计方法。专业上,p值为结果可信程度的一个递减指标,p值越大,我们越不能认为样本中变量的关联是总体中各变量关联的可靠指标。p值是将观察结果认为有效即具有总体代表性的犯错概率。如p=0.05提示样本中变量关联有5%的可能是由于偶然性造成的。即假设总体中任意变量间均无关联,我们重复类似实验,会发现约20个实验中有一个实验,我们所研究的变量关联将等于或强于我们的实验结果。(这并不是说如果变量间存在关联,我们可得到5%或95%次数的相同结果,当总体中的变量存在关联,重复研究和发现关联的可能性与设计的统计学效力有关。)在许多研究领域,0.05的p值通常被认为是可接受错误的边界水平。
