我正在尝试使用 VBR 设置 V0 将 CD 翻录为 mp3。在早期版本的 K3b 中，您可以配置 LAME 命令字符串。但在 19.12.3 版本中，LAME 配置设置中的屏幕已替换为最大、平均和最小比特率条目：

K3b 中的可变比特率配置屏幕

但是，无论我在这里指定什么（并且我确实选择了可变比特率），翻录的 mp3 文件的媒体属性显示：

编码设置 -mj -V 4 -q 0 -lowpass 17.5 --vbr-new -b -32

比特率在 160 左右。所以它总是在 V4 翻录，但我想要 V0。我尝试更改最小和平均比特率条目，但无济于事。我怎样才能让 K3b 以 V0 撕裂？

尝试使用 ffmpeg 将 wav 文件转换为 mp3 时，我继续收到此错误。

这是我正在运行的命令

ffmpeg -i 11_22_40AM.wav  -acodec mp3 11_22_40AM.mp3

这就是错误

[gsm_ms @ 0x5567d18626c0] Packet is too small
Error while decoding stream #0:0: Invalid data found when processing input

以及由命令引起的所有输出

我是 Puddletag 的普通用户，我最近尝试编写一个操作来格式化 .mp3 文件轨道标记，以将前导 0 添加到单个数字值。

我通过将操作设置为使用格式值函数并将字段设置为标题，并将格式字符串设置$num(%track%, 2)为如下所示来做到这一点。 如上所述的功能窗口图像

理论上，这应该只格式化轨道值，但在我的情况下，这会格式化所有选择的字段。

我在 Ubuntu 19.10 上使用 Puddletag 1.2.0。

感谢您提供的任何帮助。

重现的完整步骤

  1. 打开 Puddletag 并导航到包含文件的.mp3文件夹。
  2. 选择任意字段组合。
  3. 运行上述操作。

所以我配置了 ARM，它对 flac 文件正常工作。但是，当我为 mp3 设置它时（我是为其他人做的，他们更喜欢 mp3）它不起作用。

从理论上讲，这个脚本应该下载一个 mp3 文件并将其标题设置为“cooltitle”，并将其艺术家设置为“coolartist”。但是当我使用 rythmbox 打开文件 test.mp3 时，它没有显示正确的标题和艺术家。

有谁知道为什么这不起作用或如何解决它？

据我所知，默认的 Brasero 应用程序在被要求将大量 mp3 曲目刻录到多个 CDR 时根本什么都不做。我知道它的一些支持应用程序（cdrdao 等）的权限问题，修复这些问题并不能解决我看到的基本问题，即“刻录多个磁盘”选项完全没有任何作用。

这只是一个已知问题（例如底层工具的权限问题）吗？我意识到现在没有太多人刻录老式音频 CD。

对不起，这是 16.04，我很抱歉没有澄清。

可以使用 Brasero 成功地刻录包含适合单张普通音频 CD 的mp3 文件组的音频“项目” 。
