lossy describing audio compression

同義詞
  • compressed

    broader; covers both lossy and lossless shrinking, so it doesn't say detail is lost

  • degraded

    stresses the worse quality of the result, not the method that caused it

反義詞
  • lossless

    shrinks a file with no loss of detail; the direct technical opposite

文法句型

lossy + noun

用法筆記

Almost always used before a noun (lossy format, lossy compression, lossy codec) rather than after 'be'. Contrasts directly with 'lossless', which keeps every bit of the original.

常見錯誤

❌This photo is lossy.
✅This photo is saved in a lossy format.
💡'lossy' describes the method or material, not the finished file itself.
❌lossy data' (meaning corrupted data)
✅lossy compression
💡the word labels the process that discards detail, not data that is simply broken.
