Troubleshooting AAC to DSF Conversion

  • !Clicks or pops in the converted DSF → sample rate conversion can introduce artifacts; use a clean multiple of the source rate
  • !DSF file has silence at the beginning or end → trim the source AAC file before converting to avoid unnecessary padding
  • !Stereo image collapsed after converting AAC to DSF → verify that the converter preserves channel mapping for multichannel audio
  • !The converted DSF clips or distorts at peaks → reduce the gain or apply a limiter before conversion to prevent hard clipping
