I m 寻找最小规模的音频文件,供一些javascript打工。
其中,Ogg 通常小于<代码>MP3。 两者都远小于未压缩的WAV。 当然,可能还有其他因素在贵网站发挥作用,如质量(在大多数用途上,其差异不大)和浏览器支持。
档案尺寸只会影响向用户机器下载档案所需的时间。 它赢得了一定数量的 determine印执行速度。 你的守则可能会造成业绩下降(除非你将其缩小到音频文档的档案规模)。
<<0>2019:>>>>> >mp3 是你的朋友。
Type | Compression | Browser Support | Quality | Size
---------------------------------------------------------------------------
MP3 | Compressed | Great | Depends on compression | Small
OGG | Compressed | Not so good | Depends on compression | Smallest
WAV | Uncompressed | Good | Best | Large
编外文件为16比特,8千赫(即每秒128千兆克),而标书3可压缩为每秒16千兆克。 体积为x10大于mp。 这一比例非常具体。 Wav是一种原始格式,而mp3是一种压缩的音频格式。 ogg 更多是包装格式。 它可以总结Speex压缩的录音,Speex(www speex org)是一种基于CELP的非常高效压缩技术。
Tips - 利用uda(审计来源伪造净额)对最小尺寸的原始产品(如果可能的话,可使用8千赫兹16平方位)进行分类和储蓄,将这一产出转化为第三代。 以通用格式(mp3/wav)保持音响是一个好的想法。
西维协会的档案数量非常庞大,而且令人遗憾的是, o格没有得到普遍支持,因此MP3很可能是你最好的床。 如果你想尽快确保文件下载,那么你就应当研究一下你再次使用的压缩办法。 如果你没有机会获得压缩选择,则试图下载录音编辑方案,如Audacity。 打开档案,然后作为MP3再出口。 争取以相对较低的比值(128k、64k或更低)保存健全的档案,看看回的质量是否仍然可以接受。
IMHO - 48kb/s MP3
最好的答案可能是在两者之间保持平衡。
档案数量(带宽到用户的类型)
运行成本如何高(对低功率机器来说较好)
质量(用户如何看待)
我怀疑你的情况,因为你对其他操作守则感到关切,因此,你想要采用最低处理能力的形式。
这里的2个变量是比值和比值深度,但环状3确实考虑到深度。
这里我的理解是:
因此,我关于一般目的的建议是选择代谢和48千分之低的比照率。
Not that it will make a lot of difference, most websites are accessed via phones that are mono anyway. Mono WAV files take up less space than stereo and lower bit depths take up less. Also Audacity is a software that can convert between audio types.
我作为音响工程师的专业观点是,掌握音频能够适当取得最佳结果,但这在另一个论坛上又是一个议题。
