Yes — drop a folder of AMR files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.
Will the AIFF keep the same sample rate as AMR?
+
默认是 (48 kHz AMR 48 kHz AIFF) 。 如果您需要下调兼容性样本( 例如, 96 kHz 44.1 kHz 用于 CD 燃烧), 高级样本率选项使用高质量的重标来进行此操作 。
是的 — 上传 AMR 文件由孤立的工人处理, 并在几分钟内删除。 我们从不玩、 储存或分享音频内容 。
转换 1小时 AMR 到 AIFF 需要多长时间?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour AMR → AIFF finishes in 6-12 minutes.
Why is the AIFF file louder / quieter than the AMR source?
