Find Duplicate WAV Files by Content Hash

Source: R/find_duplicate_wavs.R
find_duplicate_wavs.Rd

Searches a directory and its immediate subdirectories for duplicate WAV files based on MD5 hash of file contents. Returns one representative file path for each set of duplicates found.

Usage

find_duplicate_wavs(dir, parallel = TRUE, n_cores = NULL)

Arguments

dir

Character. Path to the directory to search. Must exist.

parallel

Logical. If TRUE, use parallel processing for hashing. Default is TRUE.

n_cores

Integer. Number of cores to use. Default is NULL (auto-detect).

Value

A named character vector where:

  • Names are MD5 hashes of duplicate file contents

  • Values are representative file paths (first occurrence) for each duplicate set

Returns empty character vector if no duplicates found. Returns NULL invisibly if no WAV files found.

Details

The function searches the specified directory and its immediate subdirectories (one level deep) for WAV files. File matching is case-insensitive. Duplicates are identified by computing MD5 hashes of the binary file contents.

Requires the digest package to be installed.

Examples

if (FALSE) { # \dontrun{
# Find duplicate WAV files
dups <- find_duplicate_wavs("/path/to/audio/library")

# Print duplicate sets
if (length(dups) > 0) {
  print(dups)
}
} # }
